The Humphrey 320 Series 1/4-inch ported 3-way direct acting solenoid valves have achieved multi-million life cycle capability in both testing at Humphrey Products and in actual customer applications. The key to this exceptionally long life is the controlled, short-stroke balanced poppet design. This permits rapid cycling with excellent flow characteristics, eliminates the need for lubrication and is tolerant of impurities in the air system, ensuring positive sealing.
The 320 Series valves have a Cv of 1.0 and are rated for air and inert gas from vacuum at 28-inches Hg to 125 psig, at ambient operating temperatures from +32o to +125oF, with a maximum leak rate of 4cc/minute @ 100 psig. The 320 Series valves are designed for inline mounting, or for insertion into Humphrey-designed custom manifolds to create compact assemblies that can fit into tight or unusual spaces. The 320 Series valves feature a continuous duty coil with a power consumption of 8.0 watts, flying leads and a push, non-locking manual override as standard. Optional locking manual override is also available. The valves come in a range of AC and DC voltages. Options include DC surge suppression, AC MOV and a DIN-type plug in connector. Humphrey also offers a 420 Series 4-way direct acting solenoid valve.
