EH 40 Series High Pressure Valve

1/4" - 1/2" PIPE SIZE
50 PSIG- 100 PSIG MINIMUM PRESSURE REQUIRED

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.

APPLICATION:

The EH40 series is ideal for flow control of high pressure air, water, compressed natural gas (CNG), hydrogen, nitrogen, and other gases or light liquids compatible with the materials of construction. The mounting orientation is critical, requiring the valve to be mounted with the solenoid vertical and on top.
