EH70 Series High Pressure Valve

No Minimum Pressure Required

OPERATION:

Valve opens when energized and closes when de-energized. When the coil is energized the pilot valve opens, relieving the pressure above the piston, which is then lifted from its seat by the plunger. Upon de-energizing the coil, a spring closes the pilot valve and opens a bleed passageway to permit pressure to build above the piston and seat it. The normally open valve operates similarly, closing when energized and opening when de-energized.
