The 310/410 series solenoid valve from Humphrey Products Co. (Kalamazoo, MI) is a compact 1/8-in., ported 3-way and 4-way, direct- acting solenoid valve that provides high reliability in various pneumatic applications. The short-stroke balanced poppet design permits rapid cycling, requires no lubrication, and is tolerant of impurities in the air system, ensuring positive sealing.
The 310 Series valves have a 0.12 CV; the 410 Series valves have a 0.14 CV. Both valves are rated for air and inert gas from vacuum at 28-inches Hg to 125 psig. The continuous duty coil consumes 4.0 Watts, comes with flying leads, and is available in a range of AC and DC voltages. A push, non-locking manual override is standard. Options include DC surge suppression and AC MOV, plug-in DIN-type connectors, locking override, and built-in flow controls.
