Humphrey”s310/410 Series valves are 1/8″ ported three- and four-way direct-actingsolenoid devices designed to meet a variety of pneumatic applications.Valves of the same series can be mounted in-line or on a sub-base or combined on the same manifold. In addition, custom-designoptions are available for compact manifold assembly incorporating thevalve components. This reduces the overall manifold dimensions to fitin a tight or unusual space. The valves have a short-stroke, balancedpoppet design that permits rapid cycling, requires no lubrication, andis more tolerant of impurities in the air system to ensure positivesealing. The 310 Series valves have a 0.12 CV; the 410 Series valveshave a 0.14 CV.  Both valves are rated for air and inert gas fromvacuum at 28-inches Hg to 125 PSIG. The continuous-duty coil has apower consumption of four Watts, comes with flying leads, and isavailable in a range of AC and DC voltages. A push, nonlocking manualoverride is standard.
