Product Details
250 Series 1/4 pipe "Interface" valves are ultra-low pilot pressure bleed valves. Pilot signaling pressures as low as 0.1 PSIG effectively blocks the bleed orifice and the internal, full pressure completes the shift to the actuated position. Primary valve is classic Humphrey diaphragm poppet principle. Ideal for fluidics, proximity switching and air jet sensing.
