Solenoid Valves

High Flow 3-Way Dual-Coil Solenoid Valve

The High Flow 3-Way Dual-Coil Solenoid Valve utilizes a two-stage poppet to allow over six times more flow when compared to the standard piloting solenoid valve. It also incorporates an additional coil to provide electrical redundancy for added safety. In exchange, the package size and weight are slightly increased when compared to the single coil configuration. This design utilizes MultiSeal® technology, eliminating the need for O-rings, simplifying port layout, and offering significant space and weight savings.
