How to Order

Specifications

The Series 91000 Self-Operating Temperature
Regulator is the preferred choice of original equipment
manufacturers, mechanical contractors and specifying
engineers. This regulator requires no external power
source and is ideal for regulating the temperature of
tanks, process streams and various industrial
equipment. The actuator is noted for its rugged, die cast
aluminum housing. The Model 91400 is furnished with
an adjustable dial thermometer to allow the operator to
verify the process temperature. The Model 91600 Fail­Safe Actuator is designed to cause the valve to fail in
the safe control position (open in a cooling application,
closed in a heating application) should accidental
damage to the thermal system occur, resulting in loss of
the pressure charge.

For optimal performance,the service conditions (medium,
flow, temperature, inlet and outlet pressures) of the
application must be considered when selecting a valve.
Please refer to the Valve Selection Section of this catalog.
For applications where the process media may be corrosive
or contained under pressure,the use of a thermowell is
required to prevent damage to the regulator bulb and
facilitate its removal from the process. Improper
application may cause failure of the valve, resulting in
possible personal injury or property damage.
