Piston valves are serviceable and reliable valves that are well applied to isolation use in steam and condensate systems. Recently, Spirax Sarco, globally recognized manfacturer of steam system componentry, introduced their PV4 and PV6 lines of piston isolation valves targeted at steam and condensate applications.
The new valves are available with carbon steel or stainless steel bodies, with the internals of both being stainless steel. Screwed, socket weld and butt weld connections are available in 1/2″ through 2″ sizes. The operation is unidirectional, so installation must have the system flow according to the arrow on the body. The only other installation restriction is that the handwheel should be above the valve body.
Accommodated pressure and temperature ranges for the PV4 and PV6 will be suitable for a broad range of steam and condensate applications.
