Sales Manual Section 160
PRODUCT SPECIFICATION RT-1006-Bl
FEATURES
1. Safety type. Failure due to loss of thermostatic
charge automatically moves direct-acting
(heating) valve to fully closed position or

3. Chevron "Lifetime" stem packing made of Teflon
or EPT Rubber U-cup for water service.
4. Quick-detach valve stem construction permits
easy valve change.
5. Sturdy construction with cast iron frame.
6. Variety of sensing bulb forms and materials. (See
inside pages)
7. Valves in wide range of sizes, actions, styles,
materials, etc. for many services. (see inside
pages).
8. Capillary selection (see inside pages).
9. Setpoint Adjustment Wheel
Self Actuated
Temperature Regulator
RT-1006-Bl "Fail-Safe" Series
Prevents overheating when
thermal system is inoperative.
GENERAL
Without need for external power, Robertshaw
Self-Actuated Temperature Regulators (SATR) offer
final control of the temperature of a liquid, an air
space or flow, or gas flow for domestic, equipment,
process, space, etc. on heating or cooling service.
The SATR sensing bulb is installed in the medium
being controlled while the SATR valve is located on
the supply line of the medium used as the heating
(steam, hot water) or cooling (water, ethylene glycol,
brine) agent. The SATR regulates the heating or
cooling medium flow to maintain the desired
temperature at the sensing bulb location. Robertshaw
SATR are usually cataloged to detail the two-way
direct acting (close on temperature rise) type valves
for heating service. Two-way reverse-acting (open on
temperature rise) and three-way valves are equally
available for cooling service.
Sizes: Direct-Acting, 1/4" - 1"
Reverse-Acting, 1/4" - 2"

RT-1006-Bl SERIES
The RT-1006-BI series is a non-indicating design
suited to heating or cooling applications where
temperature overheating is of basic concern. This
series is designed and constructed to push the stem
downward in the event of a loss of thermal charge.
It will close a direct-acting valve or open a reverse-
acting, on charge lost, to prevent the overheating
associated with other temperature regulators.
For larger valves, greater valve stroke or higher
pressure drops see the RT-1007-Al series.
For cataloging and pricing purposes, the RT-1006-BI series is detailed with
direct acting valves for heating, 8 ft. capillary (copper tube/ brass armor), type
12B (threaded bushing) copper sensing bulb, cast iron frame and other non-listed
parts of non-ferrous metals. Alternate specifications are available.

VALVE SIZING
Valve sizing is critical to control and life of regulator.
Use Robertshaw's "Flo-Rule" Valve Sizing Slide Rule and
valve Cv chart or contact our representative or factory. The
application requirement can frequently be satisfied by one
or two sizes smaller valve than the supply pipeline size.
ALTERNATES INCLUDE:
Capillary:
Length ............................................ 1 ft. to 50 ft. or more
Materials ..........Copper tube with brass armor (standard)
or 304 stainless steel tube with SS braid
Sensing Bulbs:
Type12B .............................................. Copper (standard)
Type 12BP ........................................... 316 stainless steel
Type 12B or 12BP .........................with "dead extension"
Type 54 ................................... Copper, externally finned,
Plain (54A),
Bushed (54J),
Flanged (54K)
Type 6 ........................................... Plain for open vessels,
Copper with copper tube and brass armor (6A),
316 SS with 304 SS tube and no braid (6AP)
Separable Wells (for sensing bulb protection or ease
or removal):
Material: ................................................................ 316 SS
Type GA or GA with lagging extension ...........................
Mounting thread one size larger than bulb size
Type GB ..............Mounting thread same size as bulb size
Valves: ...................................Types A, FA, MA, MAS, WA
as illustrated
Note 1- IMPORTANT - If valve seat leakage can cause a
problem or a hazard, the following should be taken into
account. Maximum leakage of new valves: single-seated
Types A, WA - 0.05% of full open valve capacity;
single-seated balanced Types MA, MAS - 0.01% of full
open valve capacity; double-seated Type FA - 0.5% of full
open valve capacity. This leakage will usually increase
somewhat as the valve seats wear in service.

** Bulb sizes for ranges beginning below 120° F. are necessary to
provide "cross ambient" charge. This assures operation with
ambient temperatures either above or below the control setting.
Under some conditions, smaller bulbs may be used with lower
ranges. If the larger bulb cannot be used, consult the factory or
nearest representative.

The RT-1007-Al series is a non-indicating design suited
to heating or cooling applications where temperature
overheating is of basic concern. This series is designed and

loss of thermal charge. It will close a direct-acting valve or
open a reverse-acting valve, on charge loss, to prevent the
overheating associated with other temperature regulators.
The RT-1007-Al series can be supplied with small valve
sizes; however, the more economical RT-1006-BI is
normally used with the advantage of smaller bulb size, etc.
For cataloging and pricing purposes, the RT-1007-Al series is detailed with direct acting valves for heating
service, 8 ft. capillary (copper with brass armor), 12 type (threaded bushing) copper sensing bulb, cast iron
frame and other non-listed parts of non-ferrous metals. Alternate specifications are available.
