Piston Valve

The Sealing System
Astainless steel piston enclosed by two resilient valve ring forms thesealing system. The sealing area is the surface of the piston. Theupper valve ring ensures tightness against the atmosphere while thelower valve ring provides sealing across to ports.

Steam and superheated water
Miscellaneous types of gases (e.g. Oxygen, Hydrogen, Nitrogen, etc. )
Heat transfer oils
Chemicals
