| 3-Way High Flow Piloting Solenoid Valve | |
A natural evolution of our field proven piloting solenoid valves, these miniature high flow valves set a new standard in reducing space, weight and power consumption. Valve elements are based on the low leakage, high reliability designs used in Lee check and shuttle valves. Our MultiSeal* radically simplifies port layout, offers significant space savings, reduced machining costs and higher reliability than traditional sealing methods.
