SH-900 Series Bimetallic Steam Traps

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 sufficiently hot to pull on the trap’s valve stem, closing the valve.
