Threaded Piston Valves
Pneumatic Piston Valve
A pneumatic piston valve is a Y-body on-off valve that opens and closes rapidly under compressed air control via a pneumatic cylinder (piston actuator) mounted on top. With single acting, normally closed design, the spring closes the valve when air supply is cut; it is used for automatic shutoff in steam, hot water, air and process fluid lines.
Supplied with AISI 316 stainless steel body and PTFE seat in sizes from 1/2″ to 2″, pressure class PN16 and up to 180 °C. Control air range is 3–8 bar.
