New 3-way High Flow Miniature Piloting Solenoid Valve
Description
WESTBROOK, CT - The Lee Company’s miniature 3-way High Flow Piloting Solenoid Valve offers dramatic space and weight savings as well as high reliability and performance. Available in a single coil configuration, the compact valve weighs just 4 ounces and uses only 7.8 watts at 28 vdc. Operating pressure is 3,000 psi, and minimum flow at that pressure is 4.0 GPM (300 Lohms).
A unique plunger design and innovative materials in the magnetic circuit result in a miniature, low power consumption solenoid with an unusually efficient force/stroke relationship.
The use of the patented Lee Multi-Seal(r) enables the hydraulic portion of the valve to be extremely small and compact. This new sealing technology eliminates conventional O-rings and back-up rings, and radically simplifies port layout by allowing two ports to be sealed in the same axial plane.Specs
