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.

RT-1011-BI SERIES
The RT-1011-B1 series is an extension of the workhorse
RT-1003-D1 series. It is the design result of trying to make
the non-indicating RT-1003-Dl series with all exposed parts
of the upperworks in 18-8 SS. This series extends the service
life of SATR units installed where the bellows and other
relatively thin parts are subjected to corrosive attack from
fumes, vapors, etc. from plating or process vats, tanks, etc.
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 can frequently be satisfied by a smaller sized
valve than the supply pipeline size.
The RT-1011-B1 series is available with any of the ranges
listed below. The range should be selected so that the setpoint
falls within the upper third of the range span.
10°F - 55°F
30°F - 80°F
50°F - 105°F
75°F - 130°F

Plain (54A),
Bushed (54J),
Flanged (54K)

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, CSS, FA, MA, MAS, WA, WCSS, WD
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, CSS, WA, WCSS - 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; single seated Type WD – 1% of full
open valve capacity. This leakage will usually increase
somewhat as the valve seats wear in service.
NOTE 2 - IMPORTANT - Damage to or failure of the
thermal element with loss of charge will ordinarily result in
the regulator going to the "cold" position. The valve stem
moves "up" (toward the bellows) - thus a "direct-acting"
valve will fully open, a "reverse-acting" valve will close, and
a 3-way valve will open the bottom port.
For cataloging and pricing purposes, the RT-1011-B1 series is detailed with direct-acting valves for heating service, 8 ft. plain
304 stainless steel tube capillary, 12BP type (threaded bushing) in stainless steel with stainless steel sensing bulb, cast stainless
steel frame and non-listed parts in stainless steel. Alternate specifications are available.

** 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.
