Non-Indicating

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 Fail-Safe 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.
