The Model EH21 is a two way normally open (2/2 NO) high pressure stainless steel solenoid valve with 1/8" NPT ports in either a standard or manifold body, suitable for hazardous locations. Various coil options available.

1/8" NPT Stainless Steel Solenoid Valve with orifice sizes from 1/32" to 3/32" and pressures up to 3000Psi. Grommet or Conduit Coil Housing as standard with European Style DIN Coils as an option.
The standard valve has a Kel-F Pin seal. Extended orifice guides the sealing pin for perfect alignment.

This valve uses the same kinetic energy impact mechanism as the EH22 but incorporates an internal rocker arm to reverse the action of the sealing pin. The kinetic energy of the plunger is applied to one end of the rocker arm when the coil is de-energized. This lifts the sealing pin, on the opposite end of the rocker arm, against the force of high pressure. A return spring acts directly on the pin, sealing the orifice when the coil is energized. For use on Air and other non-corrosive gasses, water and oil.
