Steam Water Mixing Valve - Model F5 - Sizing
Chart Instructions
Checklist for sizing the F5 steam water mixer
Information Required to Size the Valve:
• Running water pressure drop*(psi)
• Steam pressure drop** (psi)
• Water temperature rise required (dT) °Fahrenheit.
• Required flow (U.S. gpm)
NOTES:
* The ‘Water Pressure Drop’ is the difference between the running water pressure at the water inlet port and the outlet port.
** The ‘Steam Pressure Drop’ is the difference between the running steam pressure at the steam inlet port and the pressure at the outlet port.
To Size the Valve:
1. Determine the cold water capacity of the valve using the “Cold Water Capacity” column with the ‘Water Pressure
Drop’ column.
2. Using the ‘Steam Pressure Drop’ column, locate the steam pressure available at the valve steam inlet port.
Determine the ‘Temperature Rise’ required by subtracting the inlet water temperature from the desired water
temperature desired. Go across the columns to locate the temperature rise required to find the flow (U.S. gpm)
the F5 can heat to the required temperature..
3. Compare the capacities found in steps 1 and 2. The LOWER of these two capacities is the maximum amount of
hot water that size valve can produce to the desired temperature.
NOTE: A minimum flow rate must be established for there to be effective mixing, and temperature control.
The approximate minimum flows for effective stream water mixing are:
F5025
4 (15) U.S. gpm (lpm)
F50406 (23)U.S. gpm (lpm)
F5050
20 (100)
U.S. gpm (lpm)
EXAMPLE:
Using the 1” size valve (F5025).
Assume the running water pressure drop is 60 psi (4.0 bar), and the steam pressure drop is 40 psi (2.5 bar). The 1”
(25 mm) valve can pass 72 U.S. gpm (268 lpm) of cold water, but can only heat 14 U.S. gpm (54 lpm) with a 100°F
(50°C) temperature rise.
Therefore the capacity of the mixer for this case is only 14 U.S. gpm (54 lpm).
If the steam pressure could be raised to 100 psi, the capacity of the same unit would be 35 U.S. gpm (152 lpm),
100°F (50°C) temperature rise.
Safety features of the F5 valve when coupled with the Emech™ G1 actuator:
• If the cold water supply fails the valve will be closed within approximately two seconds.
• If the temperature sensor fails the valve will be closed within approximately two seconds.
• The G1 has a manual override handle enabling operation of the valve when there is no power supply.

2.0 - Steam Water Mixing Valve - Model F5 - Installation
When installing the valve in line, be
sure to follow good practice using
either sealing tape or thread adhesive
in the joints.
The valve may be attached straight to
the pipe work.
Note: Be sure to consider the ease
of removing the valve should this
become necessary in the future. See
images 3 and 4 for typical installation
methods.
Note: For valve maintenance, the
bonnet screws can be removed and
full access to the internal components
is possible.
The valve my be connected to the
pipe work with a union style of fitting
(image 3).
CAUTION: Prior to installation ensure that the pipes leading to the valve are clear from debris which may block or damage
the valve on commissioning.
WARNING:
Only trained personnel familiar with pipe work and pressure systems should install and maintain Emech equipment. Failure to do so may result in serious personal injury!
WARNING:
Depressurize pipe work to atmospheric pressure and drain all fluids from the pipe work before working on the
valve. Failure to do so may result in serious personal injury!
WARNING: Ensure that the intended maximum operating pressure of the line does not exceed the pressure rating of the
valve. Failure to do so may result in serious personal injury!
WARNING:
Non return valves are strongly recommended upstream of the valve inlets. Failure to install them may cause
undesirable back-flow and may result in serious personal injury and or equipment damage!
WARNING:
The valve must be supported adequately so as not to over stress the pipe work and or the valve body. See
Figure 5 and Table 1 below for the maximum nozzle loads on the valves. Application of loads above these
values may result in serious personal injury and or equipment damage!

2.1 - Steam Water Mixing Valve - Model F5Recommended Installation
2.1 Recommended Installation
All Emech valves and actuators are shipped fully assembled and factory set to Factory Default Settings
as a standard. Any requirement for customised Settings or Software settings will need to be
communicated at the time of order placement on the Factory.
Step 1: Location Considerations
For F5 valves mounted with an Emech G1 electronic actuator ensure the installation
locations offers suitable access to the electrical connection terminals, the manual
override handle, actuator power switch, display and keypad.
Do not install the actuator near or in high pressure wash down areas. The units must
NOT be installed upside down. For manually operated F5 valves ensure suitable
access to the handle for safe operation.
Step 2: Recommended Installation
See Figure 2.6 (page 14) for a recommended F5 valve installation schematic.
MUST HAVE
• Check valves (poppet style) MUST be fitted upstream of the valve inlet ports
and as close as practicable to the inlets.
• Pipe work adequately supported.
• A 24Vdc regulated power supply.
RECOMMENDED
• Isolation valves are RECOMMENDED on the supply lines.
• A failsafe solenoid operated spring to close isolation valve is highly RECOMMENDED for over
temperature
• failure modes (see item 2 on figure 2.6).
• Ensure mechanical protection of the wiring (e.g. use armour conduit).
• It is RECOMMENDED to place wiring in screened condui or cables.
• Ensure pipe works are straight for as long as practicable to the Emech valve inlets and any cable condit
is fully sealed on both ends against water ingress.
• Use appropriate inlet pipe diameters and supply pressure to cope with required application flows.
CONSIDERATIONS
• Consider strainers if water supply carries pipe scale or other particulates that may damage valve seat and
seals.
• Consider gauge points for temperature and pressure on inlets and outlets.
Manual Operations Considerations
• By setting the position of the “stroke limiting” stop, an approximate maximum temperature setting can be
made. This is a safety feature to minimize the possibility of operator injury. Handle kits are supplied with
fitting instructions (CPMI0029).
• The flow rate control can be achieved by either a throttle valve on the inlets or outlet, or by presetting the
supply pressures. For most circuits throttle valves at the mixing valve inlets work best.

5.0 - Steam Water Mixing Valve - Model F5 Mounting Emech™ G1 Actuators
Note: The actuator may be mounted in any
one of four positions.
The instructions below explain how to
mount the actuator facing the outlet port as
per image on page 7.
To ensure the actuator is in the ‘zero’
position, power on the actuator (a 24V DC
regulated power supply is required). Ensure
the actuator is in Temperature Controller
mode - hold mode and press down (-) on
the actuator keypad to toggle between
Temperature and Positioner mode.
Once in temperature mode, disconnect the
temperature probe from the actuator. The
actuator will move automatically to the ‘zero’
position and the keypad display will show
“E2”.
Cold Port
Set the Valve position to closed. Ensure
the notch on the spindle (image 1) points
towards the valve “0” mark and the cold port
(image 2) which is the fully closed position
for the valve seats and the default cold port
(image 2).
Place the graduated coupling (image 3)
on the spindle & ensure the zero points
to the outlet port (image 4).

Outlet Port
If the actuator is to be mounted in one
of the other three positions, rotate the graduated
coupling so that the “ZERO”
mark will line up with the notch in the
bracket (image 8) of the actuator,
when valve is fully coupled to actuator.
DO NOT MOVE THE SPINDLE FROM ITS
ZERO POSITION WHEN USING ONE OF THE
OTHER POSITIONS FOR THE ACTUATOR.
Place the center coupling (image 5) on
the graduated coupling (image 6).

Place the actuator on the valve in the
desired position (image 7). The zero mark on
the coupling (image 4) should align with the
notch on the bracket (image B).
Insert one M8 X 25 socket cap screw
into one of the mounting holes with
M8 Spring Washer and Nut. Insert the
remaining three cap screws and fasten.
Ensure the bonded washer (image 0) is on
the sensor (image 10).
Screw the sensor into the outlet port of
the valve (image 11) and tighten before
connecting the the sensor to the actuator.
Plug the sensor connector into the actuator
input port labelled “1” and hand tighten . The
actuator is now assembled
correctly (image 12).
WARNING!! DO NOT USE A WRENCH
TO SCREW THE SENSOR INTO THE
ACTUATOR.
See section 5.0 of the actuator

6.0 - Steam Water Mixing Valve - Model F5 - Commissioning
6.1 Commissioning Overview
Operating the F5 valve with excessive steam pressure can cause early wear and failure of the valve body and
components. Reducing the steam pressure will decrease relative to water pressure the decibel rating, reduce the
likelihood of pitting from cavitation and prolong the life of the valve.
Before beginning the commissioning process, note the operating angle of the valve on the actuator shaft during normal
operation. The ideal operating angle depends on the application but generally should be around 140 - 150 degrees.
If the valve is already operating within this range, reducing the steam supply could adversely affect the flow rate and
temperature at the outlet and thus the unit sized, may not be applicable for your application.
This method involves reducing the steam supply. To do this an appropriate device will need to be in line on the
steam supply side before the inlet of the F5 valve. Armstrong recommends a pressure regulating valve, ut a steam
restriction/isolation or throttling valve may suffice.
WARNING: This commissioning technique will result in out of spec water. To avoid injury to personnel
and disturbance to sensitive processes Armstrong recommends diverting the F5 outlet flow to non-sensitive
processes, re-circulation or dump (if appropriate).
The commissioning process should eliminate extreme cavitation symptoms. However if
there is no improvement by lowering the steam pressure, please contact Armstrong for an
engineered solution.

6.2 Commissioning Process
Set the actuator to control at the highest desired set point and maximum required flow rate.
For best practice two operatives will be required. One located at the keypad to view the outlet temperature
and observe the actuator shaft and the other at the steam restriction valve.
