Humphrey provides design and plant manufacturing engineers with a wide range of standard and specialty 2-, 3-, and 4-way Air Piloted Valves, capable of addressing almost any application, including those challenging scenarios that other manufacturers struggle with. These valves can be operated using smaller, more efficient piloting valves located remotely or connected to the outputs of work valves when simultaneous functions are required. Integrate your pneumatic automation with auxiliary process control by pilot operating alternate media, vacuum, or exceptionally clean, high-integrity air.
250A Series 1/4 pipe Air Pilot Valves feature the classic Humphrey diaphragm poppet principle. The unbalanced, air-spring return design assures reliable shifting and bubble-tight sealing actuated, and unactuated. Compact design permits close proximity mounting to work and fast cycling/quick exhaust. Rugged 2- or 3- way valves are available normally closed or normally open, in standard or optional brass body construction (for alternate media). Made in the USA.
