Product Details

125A Series 1/8 pipe Air Pilot Valves feature the classic Humphrey diaphragm poppet principle.

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).
