Description

The SP80 and SP100 are pilot operated bimetallic steam traps made

of cast steel. They have a built-in strainer screen to protect the pilot

valve and an external device for adjusting the discharge temperature

of the condensate. They are specially designed for high capacity

process applications.

They are not sensitive to overheating and have a bimetallic pilot

device which controls a main valve via a large diameter piston. These

steam traps can be repaired inline and operate with no loss of steam.

They quickly drain air, non-condensable gases and large quantities

of cold water on start-up.
