IPV40PKA - Pneumatic valve PVPK

The range of single acting cylinder, spring return pipeline valves is designed for high speed actuation from standard pneumatic lines, and are offered in sizes NW10, 16, 25, 40 and 50. The NW16, 25, 40 and 50 versions of the valve are available in both right-angle and in-line styles, to give you more options when you design your vacuum system.

The valves are designed for long life duties, with a MTTF of 5000000 cycles for both bellows and ‘O’ ring sealed versions providing long intervals between services.
