EH50 Series High Pressure Valve

OPERATION:

The normally closed 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 inlet pressure. Upon de-energizing the coil, a spring closes the pilot valve and pressure builds above the piston to seat it. The normally open valve operates similarly, closing when energized and opening when de-energized.
