Product Description

Class 150 Piston Valve

Full port forged steel isolation valves with a maximum operating pressure of 1973 psig/136 Barg and a maximum operating temperature of 800oF/427oC. The burnished piston and metal reinforced graphite rings provide leak-proof shut off and allow Piston Valves to be operated at higher temperatures, while also extending operating life.

Piston Valves are available in Socket Weld, BSPT, and NPT end connections. Flanged ends can be supplied upon request. Piston Valves are ideal for saturated and superheated steam, and hot water applications.
