• Allows positioning options for easy service
• Additional inlet provides a convenient location for
vacuum breakers or separate external air vents. Vacuum
breakers are required for systems with a modulating
temperature regulating valve. External air vents are
required when the trap discharges into a wet return line.

• Additional outlet provides a convenient location for a test
valve, which eliminates the need for a costly trap test
chamber and electronic monitors.

• Determine the differential pressure across the trap
(inlet pressure - outlet pressure). On applications where
the steam is controlled by a modulating temperature
regulator, the trap differential should be 1/2 psi (0.34 bar).
• Determine the capacity based on the differential pressure
and the required capacity of the trap to open against the
maximum inlet steam pressure.
• Apply a Safety Factor by multiplying required capacity
by 1.5.

Series I In-line
(continued)
• Determine the differential pressure across the trap
(inlet pressure - outlet pressure). On applications where
the steam is controlled by a modulating temperature
regulator, the trap differential should be 1/2 psi (0.34 bar).
• Determine the capacity based on the differential
pressure and the required capacity of the trap to open
against the maximum inlet steam pressure.
• Apply a Safety Factor by multiplying required capacity
by 1.5.

Steam Traps
STEAM TRAPS
Float and Thermostatic Steam Traps (continued)
Capacities (Series C and X)
• Determine the differential pressure across the trap
(inlet pressure - outlet pressure). On applications where
the steam is controlled by a modulating temperature
regulator, the trap differential should be 1/2 psi (0.34 bar).
• Determine the capacity based on the differential
pressure and the required capacity of the trap to open
against the maximum inlet steam pressure.
• Apply a Safety Factor by multiplying required capacity
by 1.5.

How to Select
The trap capacity should be selected based on the
minimum differential pressure between the inlet pressure
and outlet pressure. The trap seat must be capable of
opening against the maximum inlet steam pressure. When
the traps are used on applications where the steam is
controlled by a modulating temperature regulator, the trap
is normally selected to handle the full condensate load
including safety factor at 1/2 psi (.034 bar) differential
pressure.
For selection information, please refer to “Selection
Guidelines” on page 129.
For computer aided selection of Inverted Bucket Steam
Traps, please refer to the “Steam Specialty Component
Selectors” on the Hoffman Specialty website,
www.hoffmanspecialty.com or, for a stand-alone version
of EPS-PLUS, contact your local Hoffman Specialty
Representative (see back cover for listing).

Regulators
• For continuous or dead end service within .01% leakage
of the valve’s rated capacity
• Minimum differential pressure:
Model 2100, 2200 & 2300 ......15 psi (1.0 bar)
Model 2150, 2250 ...................3 psi (.2 bar)
• Maximum differential pressure 150 psi (10.3 bar). A two
stage reduction should be used for pressure drops
greater than 150 psi (10.3 bar). Models 2150 & 2250
have maximum 30 psi differential pressure

Note: Capacity based on saturated steam at valve inlet. Pressure differential must be at least 15 psi (6.9 bar) for valve to operate.
†For inlet pressures below 30 psig (2.1 bar), refer to the Low Pressure Steam Capacity Chart, Models 2150 and 2250, page 48.
††When the outlet steam pressure is 50% or less of the inlet pressure, always use the lowest outlet pressure shown in the capacity table.

! WARNING
Series 1140 and 1141 Regulators fail open.
An alarm or cut-off must be installed on
applications where overheated water could
cause harm.
Failure to follow this warning could cause
serious burns, personal injury, or death.
1. Determine body style based on type of service. See
Selection Data Chart below.
2. For complete units provide the 6 digit part number and
description in the following format.
1140 TMP REG – Body Code – Body Size –
Temperature Range
For example, to order a 1 inch NPT, 02 body, 140° to
180°F (60-82°C) degree range unit with standard bulb
and capillary, your order should have the following:
Hoffman Specialty Part Number – 400117 Description –
1140 TMP REG 02 1.0 140 – 180
Select a range with the operating set point in the mid or
upper portion of the range.
3. Units may also be ordered as Body Bracket Assemblies
with separate Actuators. This offers a large variety of
applications while maintaining low stock.

offman Specialty Tempering Valves are designed to
control temperature in water mixing applications
such as radiant floor heating, domestic hot water
and industrial processing. They can also be used to divert
flow in cooling systems. Series 21 Valves can be used for
residential, industrial, commercial or institutional
applications.
Series 21

Model 21LT 100–140°F (38–60°C)
• Maximum pressure 125 psig (8.6 bar)
• Maximum hot water supply temperature 235°F (113°C)
Model 21 provides wide temperature adjustment range for
hot and cold water mixing in applications other than
domestic hot water.
Model 21H provides widest temperature adjustment
range for radiant heating applications where accurate
temperature control is less critical.
Model 21LT provides the greatest accuracy of
temperature control in mixing domestic water.
! WARNING
Do not use Tempering Valves as antiscald devices. Tempering valves may
need to be used in conjunction with an
anti-scald device.
Failure to follow this warning could
cause serious burns, personal injury or
death.

Steam Traps
Selecting and Sizing Steam Traps
Selecting the proper steam trap is important in effective
operation of steam systems. Steam traps are automatic
valves that open to pass condensate and close to prevent
the flow of steam. The functions of a steam trap in a
steam system are to:
• Vent air from the system so steam can enter
• Hold steam in the system until the steam latent
heat is removed
• Drain condensate from the system as it is formed
after the latent heat is removed.
Removing condensate from piping helps prevent erosion
and water hammer. Removing condensate from heat
exchangers is required to make room for new steam for
the heating process.
There are many types of steam traps. The Steam Trap
Selection Guide Chart (page 131) points out system conditions that may be encountered and suggests the trap
type(s) that may best handle the requirement. Several
types of traps may be used for a specific application (refer
to the Steam Trap Application Guide, page 132). Use
these charts only as guides.
Factors to consider in selecting the type of trap include:
• Constant or modulating condensate load
• Constant or fluctuating pressure
• Speed of air venting required
• Trap location
The Steam Trap Criteria Comparison (page 130) identifies
additional factors that may be considered in selecting a
steam trap type.
For computer aided selection of steam traps, please refer
to the "Steam Specialty Component Selectors" on the
Hoffman Specialty website, www.hoffmanspecialty.com or,
for a stand-alone version of ESP-PLUS, contact your
local Hoffman Specialty Representative (see back cover
for listing).

TRAP SIZING
1. Determine the maximum condensate load (capacity)
requirement for the trap by one of the following:
– Referring to the manufacturers' specifications for
the system equipment.
– Approximating condensate loads using the
"General Usage Formulas " (page 128).
– Using the "CalcLoad" Load Calculator available
through "Steam Specialty Component Selector"
on the Hoffman Specialty website or ESP-Plus.
2. Determine the available steam inlet pressure at the
trap (This pressure could be different than supply
pressure at boiler.)
3. Determine the outlet pressure (backpressure) at the
trap discharge. (Pressure against the outlet can be due
to static pressure in return line or due to lifting to an
overhead return).
4. Determine the pressure differential across the trap.
(inlet pressure - outlet pressure = differential pressure).
5. Determine a Safety Factor. The Safety factor will
depend on accuracy in determining condensate load,
inlet and outlet pressures. Recommendations:
– Float & Thermostatic Trap 1.5 to 2.5
– Bucket Trap
2 to 4
– Thermostatic Trap
2 to 4
– Thermodisc Trap
1 to 1.2
6. Multiply normal maximum condensate load (as
determined above) by Safety Factor.
7. Use the Capacity Tables for the selected type of trap
to determine the trap model number.
8. Use Ordering Information Charts to determine the
part number.
Guidelines:
– The trap seat rating must always be higher than the
maximum inlet pressure at the trap.
– When a modulating control valve controls the inlet to
equipment, select a trap size with a pressure rating
greater than the maximum inlet pressure at the trap.
– Trap capacity should be checked at the minimum
differential pressure to assure complete condensate
removal under all possible conditions.
Inverted Bucket Trap Operating Pressure Selection:
• Bucket traps are offered with various orifice sizes that
determine the maximum operating pressure rating.
• A trap with a lower seat pressure rating has a larger
sized orifice than a trap with a higher seat pressure
rating. The larger orifice provides a larger condensate
rating. When the actual operating pressure is higher
than the seat rating, the pressure differential across the
seat will prevent the trap from opening. Thus, an inverted
bucket trap must be selected for the maximum differential
pressure that will be encountered by the trap.
• Trap Capacity Tables show trap capacities at lower
differential pressures than the trap rating. This allows
selection of a trap at various operating points. A trap
with a higher seat pressure rating may be used at lower
pressure differentials. However, the capacity rating at
that pressure differential will be less than the same size
trap with a lower seat pressure rating.

SELECTION GUIDELINES

Selecting and Sizing Steam Traps (continued)
Lifting Condensate to Overhead Return
Condensate must be lifted in applications where the trap
is installed below the return line.
Guidelines:
– Steam pressure at the trap inlet lifts the condensate.
Differential steam pressure across the steam trap of
1 psi (0.07 bar) will lift condensate 2 ft. (0.6 m).
– Do not return condensate to an overhead return if
modulating control valves are installed. Modulating
control valves may cause the inlet pressure to modulate
to 0 psi (0 bar). This condition will result in no differential
pressure to push the condensate into the overhead
return. When this happens, condensate will back up
into the steam chamber and result in water hammer.
Use a Hoffman condensate unit to collect condensate
and pump it to the overhead return

Series 2000
Pressure and/or Temperature Pilot Operated Steam Regulators
Series 2000 Pilot-Operated Regulators consist of a main
valve that is controlled by a single or combination of pilot
control valves.
There are a number of types of pilot control valves
available:
• Series SPS Spring Pressure Control Pilots – for selfcontained pressure regulation
• Series STPA Self-Contained Temperature Control
Pilots – for control of heated fluids
• Series AP Air Pressure Control Pilots – for remote
pressure control using air pressure
• Series 315 PNT and Series 240 PNT Pneumatic
Temperature Control Pilots – for rapidly changing
load requirement applications
Different types of pilot valves can be used in combination
to control more than one function or as a safety override.
For example, a temperature pilot may be used in conjunction with a spring pressure pilot to control both temperature and pressure. Or, a temperature pilot may be used
with a solenoid pilot to provide automatic shutdown when
an over-temperature condition occurs.

Operation of Series 2000 Pilot-Operated Regulator
Main Valve
The regulator main valve is held closed by the pressure
on the diaphragm from an internal main spring. Pilot control valves control steam flow from the upstream supply
side of the main valve to the underside of the diaphragm
of the main valve. When the pilot valve opens, steam
flows through the pilot and pressure builds in the signal
line, applying pressure under the main valve diaphragm.
This pressure force compresses the main valve spring
and the main valve opens.
Under constant steam demand, the pilot and main valve
remain relatively motionless. As the system approaches
the pilot set point, the pilot valve begins to close. Less
steam passes through the pilot and through the signal
line. Pressure in the signal line decreases as steam
passes through a small bleed orifice on the main valve.
With lower steam pressure under the main valve
diaphragm, the main valve spring forces the main valve to
close.

AND
SELECTION GUIDELINES
Series 2000
Pressure and/or Temperature Pilot Operated Steam Regulators
Main Valve with Spring Pilot
Pressure may be controlled by use of either a spring
pilot or an air pilot. The only functional difference is that
a spring pilot uses a spring to apply loading force to the
pilot diaphragm and the air pilot uses air pressure.
Under constant steam demand, the pilot and main valve
remain relatively motionless. As steam demand
decreases, the downstream pressure will rise. When the
downstream pressure rises, the pilot valve senses the
change relative to the spring or air loading force and the
pilot begins to close. Less steam flows through the pilot
and signal line to the underside of the main valve
diaphragm. The steam trapped under the main valve
diaphragm bleeds off through an orifice, allowing the
main valve to close.

Downstream pressure is sensed and fed back to the pilot
through the feedback line to the underside of the pilot
diaphragm. The downstream pressure balances against
the spring (or air pressure) force in the pilot, causing the
pilot valve to move. This movement opens or closes the
pilot valve. When the downstream pressure is below the
pilot set point, the force from the spring or air opens the
pilot valve and inlet steam flows through the pilot. The
open pilot valve allows the flow of steam through the
pilot seat and signal line, and on to the underside of the
main valve diaphragm. The force from the steam pressure pushes against the main valve spring to control the
main valve position. The main valve opens or closes in
response to its diaphragm movement.

Operation - Main valve with a Self
Contained Temperature Pilot
Temperature Pilot Operation
Self-contained temperature control pilots use a liquid-filled
bulb and bellows. The actuating force for the pilot results
from the volumetric expansion of the liquid as the bulb
temperature increases. The expansion or contraction of the
liquid controls the position of the pilot seat.
The sensing bulb is completely inserted into a downstream
heated fluid to sense the fluid temperature. The sensing
bulb is connected to a bellows by a capillary tube. When
the bulb temperature is below the set point, a spring in the
pilot keeps the pilot valve open and allows steam to flow
from the pilot inlet through the signal line, and on to the
underside of the main valve diaphragm. The force from
the steam pressure pushes against the main valve spring
to control the main valve position. The main valve opens
or closes in response to its diaphragm movement.
Under constant steam demand, the pilot and main valve
remain relatively motionless. As the bulb temperature
increases and the liquid expands, the expansion is transmitted through the capillary tube, creating an actuating
force on the bellows. The bellows expand to close the pilot
valve, shutting down the flow of steam through the pilot
seat and signal line to the underside of the main valve
diaphragm. The steam trapped under the main valve
diaphragm bleeds off through an orifice, allowing the main
valve to close.

When a temperature pilot is installed in series with a pressure pilot, the pilots perform their functions separately and
concurrently. Each pilot regulation cycle is exactly the
same as if used alone. When both pilots are open, the
main valve will open, if either pilot closes, the main valve
will close. The pressure pilot essentially acts to limit the
maximum pressure as the temperature pilot cycles to control temperature.

Operation - Main Valves with
Pneumatic Temperature Pilots
The air pilot and pneumatic temperature pilot combination
is used to control temperature in systems with rapid
changes in the required heat load. An air PRV is used to
limit the pressure of air supplied to the pneumatic temperature pilot. Limiting this supply pressure limits the air pilot
loading force and hence the main valve downstream pressure.
When the pneumatic temperature pilot senses a temperature below the set point, it delivers an air signal to the air
pilot based on the sensed temperature. This air signal
becomes the air pilot loading force. If the pressure downstream from the main valve is below the air pilot loading
force, the pilot valve diaphragm pressure is no longer balanced. The pilot valve opens and inlet steam is passed
through the air pilot to the signal line. Steam flowing
through applies pressure on the lower side of the main
valve diaphragm. This force from the steam compresses
the main valve spring and the main valve opens.
Under constant steam demand, the pilot and main valve
remain relatively motionless. As temperature rises to the
pneumatic temperature pilot set point, the temperature
pilot lowers the loading force to the air pilot. When the
loading force decreases below the force produced by the
downstream pressure, the air pilot begins to close. Less
steam flows through the air pilot and signal line to the
underside of the main valve diaphragm.The steam trapped
under the main valve diaphragm bleeds off through an
orifice, allowing the main valve to close.

2000 Ordering Information section, are based on test data.
The chart data indicates flow capacity values derived from
plots of test data that show the drop away (droop) from the
set pressure as shown in the graph below. The rated flow
capacity (A) is where the curve passes a pressure droop of

Capacity vs Controlled Pressure for Typical Main Valve with Spring Pilot
Regulator saturated steam capacities are tabulated in
charts on pages near the Series 2000 Regulator Ordering
Information. Note that all valves are available in several
trim sizes to allow flexible selections. These capacities
have been determined as outlined in PTC 19.5; 4-1959
“Chapter 4 Flow Measurement, ASME Power test Code.”
The capacities conform to Fluid Controls Institute, Inc.
specification FCI-58-1, “Definitions of Regulator
Capacities.” The capacities are based on a 10% accuracy
of regulation [2 psig (.14 bar) minimum] with the set point
at minimum controllable flow, defined as 2% of maximum
flow. Capacities are the same for whichever pilot is utilized.
116
When using the capacity tables remember:
• Values shown are maximum flow with minimum piping
restriction.
• Maximum single stage reduction 150 psi (10.3 bar)
(100 psi (6.9 bar) recommended).
• Values are for saturated steam; superheated steam
requires a correction factor.
• Outlet pressures lower than the lowest shown will have
a capacity equal to the lowest shown.
• All valves have 3 capacity ports available.
• Multi-stage reductions will have a flow capacity equal to
the lower flow capacity of the two.

How To Size Series 2000 Main Valves
Selecting the proper Series 2000 Pilot-Operated Regulator
provides accuracy and efficiency in the control and
operation of steam systems and their components. Series
2000 Regulator main valves are controlled by pilot valves.
Pilot valves of different types can be used individually or in
combination to:
– Control downstream steam pressure
– Control process temperature
– Control both downstream pressure and process
temperatures in system components
– Provide a safety override.
A complete Series 2000 Regulator consists of:
– Main valve
– Control pilot or combination of pilots
– Hardware kit
For computer aided selection of steam regulators and
pilots, please refer to the "Steam Specialty Component
Selectors" on the Hoffman Specialty website,
www.hoffmanspecialty.com or, for a stand-alone version of
ESP-PLUS, contact your local Hoffman Specialty
Representative (see back cover for listing).
Main Valve Sizing
1. Determine the available steam inlet pressure.
2. Determine the reduced steam outlet pressure.
3. Determine the capacity required by referring to the
manufacturer’s specifications for your equipment.
4. Apply the specifications (as determined in steps 1-3) to
the Full Port Steam Capacity Table to determine the
main valve size. If steam inlet pressure is below 30 psig
(2.1 bar) use the Low Pressure Steam Capacity Table
for Models 2150 or 2250 Main Valves.
– Although not recommended, a Series 2000 Main Valve
may be used for pressure drops up to 150 psi (10.4 bar).
– Main Valve noise data is available through "Steam
Specialty Component Selectors" on the Hoffman
Specialty website, ESP-Plus or upon request.
– To prevent excessive relief valve popping, the relief
valve set point pressure must be capable of being set
as follows:
Downstream
system pressure at
no load pressure
≤ 35 psig
> 36 psig
Relief valve set point pressure
= downstream pressure plus
5 psig
10 psig
5. Use the Main Valve Body Style Chart to select a model
number (based on size and pressure).
6. Use the Ordering Information Chart to determine the
part number (based on the model number).
7. Size inlet and outlet piping for velocity:
For heating or indoor applications –
4,000-6,000 ft./min. (1,219-1,828 m/min.)
For industrial or outdoor applications –
8,000-12,000 ft./min. (2,438-3,657 m/min.)
Note: Main valve noise data available through
ESP-Plus, or upon request.
8. Install drip traps ahead of regulators to drain
condensate from steam lines.
Selection Guides
Guidelines:
– To prevent seat damage and maintain control and
accuracy, do not oversize the main valve. Select a
regulator main valve that will operate between 50 - 100%
of its capacity rating. If necessary, use Normal or
Reduced Port Steam Capacity Tables.
– A Normal or Reduced Port Main Valve is recommended
for systems that will expand in the future.
– The maximum recommended pressure drop across a
single valve is 100 psig (6.9 bar). Operating with
more than a 100 psig (6.9 bar) pressure drop may
cause wire draw in the seat and excessive noise.

Procedure (continued):
4. Be sure to review the recommendations for good
practice in selecting pressure regulators.
5. Refer to the Full Port Capacity Table page 45 first for
the selection. The normal and reduced trim capacity
tables should be used if there is a possibility the
system will be expanded in the future.
6. Select the smallest regulator possible that will handle
the steam load requirements. Typically it can be found
in the Full Port Capacity Table.
7. When the outlet steam pressure is 50% or less of the
inlet pressure, use the lowest outlet pressure shown in
the capacity table.
Answer:
1. Referring to the Full Port Capacity Table, with the
conditions given above under procedure, the correct
valve to select would be a Model 2100 11⁄2" Main
Valve-Full Port.
2. Since in this example there is no supply of
compressed air in the plant nor a need to also control
temperature, a spring pilot would be selected to
handle the outlet pressure requirements. This would
be a Model SPS-30 with an adjustable range of 2 to 30
psi (.14 to 2.0 bar). Adjust the pilot to 20 psi (1.4 bar).
A model SPS-60 pilot with an adjustable range of 5 to
60 psi (0.3 to 4.1 bar) could also be used.
1. An inlet pressure of 75 psi (5.2 bar).
2. An outlet pressure of 20 psi (1.4 bar).
3. The steam load adds up to 3200 lbs./hr. (1453 kg/hr.)
as shown to the left.
Example 2.
Selection Guides
Conditions:
In this example, a pressure/temperature regulator has to
be selected to regulate the steam going into a steam to
water heat exchanger. Due to a planned plant addition in
the next 5 years, the steam system will be enlarged.
Problem:
The exchanger heats water from 50°F to 150°F (10-65°C)
and has an assumed water flow of 50 gpm (189 lpm).
The heat exchanger is limited to a 20 psi (1.4 bar) steam
pressure. Assume the steam supply pressure is 100 psi
(6.9 bar).
118
Known Data:
Temperature Rise — 150°F - 50°F = 100°F (66 - 10 = 56°C)
Water Flow — 50 gpm (189 lpm) = 3000 gph (11,356 lph)
Steam Inlet — 100 psi (6.9 bar)
Steam Outlet — 20 psi (1.4 bar) (heat exchanger limit)
Procedure:
1. Refer to table 2, page 126 to obtain the steam required
to satisfy the above conditions. This would be 2500
lbs./hr. (1134 kg/hr.) according to the tables.
2. Since it is planned to enlarge this system at a later
date, refer to the steam capacity tables for a normal
port to obtain the regulator size .

Sizing Examples
Example 2. (continued)
3. When the outlet steam pressure is 50% or less of the
inlet pressure, use the lowest outlet pressure shown in
the capacity table.
Answer:
1. Using the above data and referring to the Normal Port
Capacity Table page 46, a 11⁄4" NPT main valve with a
normal port that passes 2880 lbs./hr. (1306 kg/hr.) of
steam would be selected.
The order would be for:
One, Model 2100, 11⁄4" NPT Main Valve-Normal Port.
2. Since temperature must be controlled, a combination
of spring and temperature pilots should be selected.
This would be:
One Model SPS-60 with adjustable range of 5 to 60
psi. (0.3 to 4.1 bar) or one Model SPS-30 with
adjustable range of 2 to 30 psi (0.1 to 2.0 bar). The
pilot would be adjusted to the required 20 psi (1.4 bar).
One Model STPA-200 with a temperature range of 50200°F (10-93°C) would be selected and adjusted to
150°F (65°C) to maintain the desired temperature of
water leaving the heat exchanger.
NOTE: An alternate option is to use a pneumatic
temperature pilot with an air pressure pilot and an
air regulator. This would be:
One Model 315 PNT with a temperature range
of 50-300°F (10-149°C) adjusted to 150°F (65°C)
to maintain the desired temperature of water
leaving the heat exchanger.
One Model AP-1A Air Pressure pilot to receive
the control signal from the pneumatic
temperature pilot.
One Air PRV Regulator, adjusted to maintain a
maximum 20 psi (1.4 bar) outlet pressure.

3. Determine the available initial steam inlet pressure.
3. Determine size required:
4. Determine the outlet pressure required, based on your
heating or cooling equipment.
– For body codes 01, 02, and 02R use
Cv/Kv in capacity tables.
5. Use the capacity tables to select the regulator required.
– For body codes 05, 05R, 06 use capacity
graphs.
Example:
What size regulator is required to heat 500 GPH (1892
LPH) of water from 60°F (15.5°C) to 160° (71.1°C) [100°F
(55°C) temperature rise]? The regulator inlet pressure is
15 psig (1.0 bar) and the heat exchanger operating
pressure is 9 psig (.6 bar).
Solution:
Use Table 3 or 3A to determine the required capacity of
420 lbs./hr. (190 kg/hr.). Use the single seat body code 01
or 02 capacity tables. You can use a 1-1/4" NPT valve
rated for 572 lbs./hr. (260 kg/hr.)

2. System operating pressure
Determine the operating pressure of the steam system.
(a) The rated operating pressure of the vent must be higher than the maximum operating pressure in the steam
system. When the system pressure exceeds the vent operating pressure rating, the vent cannot open and
air will remain in the system. Air in the system produces inefficient steam system operation.
(b) On steam systems with pressures up to 125 psig, Thermostatic Traps such as Model 8C and 9C may be
used as air vents.
(c) Determine if the vent is to be installed in a vacuum system. The Model 76 Main Vent is for vacuum service.
It should be used on systems with a vacuum pump or a vapor system with a coal or wood fired boiler.
Systems converted from coal or wood fired to oil or gas should use non-vacuum vents such as the Model 75.

the vent will remain closed and air will remain in the system.
3. Connection size
Determine the NPT connection size where the vent is to be installed.
4. Capacity
Vent capacity determines the speed that air is initially vented from the system. Once the system is initially filled
with water, very little air should re-enter the system. Thus water vent capacity is relatively unimportant.

TECHNICAL INFORMATION AND SELECTION GUIDELINES
Glossary of Terms
The definitions given in this section are only those
applying to heating and particularly as used in this
catalog. Some do not define the terms for all
usages.
Absolute Humidity: The weight of water vapor in
grains actually contained in one cubic foot of the
mixture of air and moisture.
Absolute Pressure: The actual pressure above
zero. It is the atmospheric pressure added to the
gauge pressure. It is expressed as a unit pressure
such as Ibs.per sq. in. absolute.
Absolute Temperature: The temperature of a substance measured above absolute zero. To express
a temperature as absolute temperature add 460° to
the reading of a Fahrenheit thermometer or 273° to
the reading of a Centigrade.
Boiler Feed Pump: A pump that is governed by a
control that monitors the actual boiler water level;
and only adds water to the boiler when the boiler
needs it. The pump controller is mounted on the
boiler.
Boiler Feed Unit: A pre-packaged system
consisting of a tank, pump, and makeup water line
that returns condensate to the boiler
Boiler Heating Surface: The area of the heat
transmitting surfaces in contact with the water (or
steam) in the boiler on one side and the fire or hot
gases on the other.
Absolute Zero: The temperature (-460°F. approx.)
at which all molecular motion of a substance ceases, and at which the substance contains no heat.
Boiler Horsepower: The equivalent evaporation of
34.5 Ibs. of water per hour at 212° F. to steam at
212° F. This is equal to a heat output of 33,475 Btu
per hour, which is equal to approximately 140 sq. ft.
of steam radiation (EDR) .
Air: An elastic gas. It is a mechanical mixture of
oxygen and nitrogen and slight traces of other
gases. It may also contain moisture known as
humidity. Dry air weighs 0.075 Ibs. per cu. ft.
British Thermal Unit (BTU): The quantity of heat
required to raise the temperature of 1 Ib. of water
1°F. This is somewhat approximate but sufficiently
accurate for any work discussed in this catalog.
One Btu will raise the temperature of 55 cu. ft. of air
one degree F.
BSPT: British Standard Pipe Thread
Air expands or contracts approximately 1/490 of its
volume for each degree of rise or fall in temperature
from 32° F.
Air Change: The number of times in an hour the air
in a room is changed either by mechanical means
or by the infiltration of outside air leaking into the
room through cracks around doors and windows,
etc.
Air Cleaner: A device designed for the purpose of
removing air-borne impurities such as dust, fumes,
and smokes. (Air cleaners include air washers and
air filters.)
Air Conditioning: The simultaneous control of the
temperature, humidity, air motion, and air distribution within an enclosure. When human comfort and
health are involved, a reasonable air purity with
regard to dust, bacteria,and odors is also included.
The primary requirement of a good air conditioning
system is a good heating system.
Air Infiltration: The leakage of air into a house
through cracks and crevices, doors, windows, and
other openings, caused by wind pressure and/or
temperature difference.
Air Valve: See Vent Valve.
Selection Guides
Boiler: A closed vessel in which steam is
generated or in which water is heated by fire.
Atmospheric Pressure: The weight of a column of
air, one square inch in cross section and extending
from the earth to the upper level of the blanket of air
surrounding the earth. This air exerts a pressure of
14.7 pounds per square inch at sea level, where
water will boil at 212°F. High altitudes have lower
atmospheric pressure with correspondingly lower
boiling point temperatures.
136
Bucket Trap (Inverted): A float trap with an open
float. The float or bucket is open at the bottom.
When the air or steam in the bucket has been
replaced by condensate the bucket loses its
buoyancy and when it sinks it opens a valve to
permit condensate to be pushed into the return.
Bucket Trap (Open): The bucket (float) is open at
the top. Water surrounding the bucket keeps it
floating and the pin is pressed against its seat.
Condensate from the system drains into the bucket.
When enough has drained into it so that the bucket
loses its buoyancy it sinks and pulls the pin off its
seat and steam pressure forces the condensate out
of the trap.
Calorie (Small): The quantity of heat required to
raise 1 gram of water 1°C (approx.).
Calorie (Large): The quantity of heat required to
raise 1 kilogram of water 1°C (approx.).
Cavitation: Term used to describe when
condensate flashes into steam as it passes through
a negative pressure in the eye of a centrifugal
pump impeller. Steam pockets may form in the
impeller eye and then implode as they enter a
positive pressure in the impeller passage.
Centigrade: A thermometer scale at which the
freezing point of water is 0° and its boiling is 100°.
Central Fan System: A mechanical indirect system
of heating, ventilating, or air conditioning consisting
of a central plant where the air is heated and/or
conditioned and then circulated by fans or blowers
through a system of distributing ducts.
Chimney Effect: The tendency in a duct or other
vertical air passage for air to rise when heated due
to its decrease in density.

forces the disc off its seat. Flash steam, created
from hot condensate reacting to the lower
downstream pressure, builds pressure of top of the

chamber drops due to cooling from natural heat
losses. When the inlet pressure becomes greater
than the cap chamber pressure, the cycle repeats.
