Piston valves isolate steam,
condensate and process media
The PV4 and PV6 piston valves (photo) are developed for isolation purposes. They are available in NPT and SW versions, in sizes from 1/2 to 2 in. Material choices include forged carbon steel and forged stainless steel. These valves are designed to Class 800 and provide tight shutoff, suitable for steam, condensate and other liquid purposes. — Spirax Sarco, Blythewood, S.C.
