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).
