Bimetallic Steam Trap For Superheat Conditions – SH-900 Series

SH-900 Series Superheat Steam Traps operate by the effect that rising temperature has on the thermostatic bimetallic elements. At start-up, the valve is wide open, which allows a large volume of non-condensables and cold condensate to be removed from the system. When the system reaches steam temperature, the elements become...

Bimetallic Steam Trap For Superheat Conditions – Model SH-2500

The effect of rising temperature on bimetallic elements operates the SH-2500 bimetallic steam trap. It adjusts to changing conditions because the curving of the bimetallic elements, caused by increasing temperature, compensates for increasing pressure. At start-up, the valve is wide open, which allows a large volume of non-condensables and cold...
