Piloting Single-Coil Solenoid Valve

The Piloting Single-Coil Solenoid Valve was designed to be the most reliable, efficient, and compact solenoid valve available. This design utilizes MultiSeal® technology, eliminating the need for O-rings, simplifying port layout, and offering significant space and weight savings. The innovative coil design provides low power consumption and fast response times. The valve was qualified through extensive testing and has been field-proven through decades of use in demanding applications.
