The Model EH22 is a two way normally closed (2/2 NC) high pressure stainless steel solenoid valve with 1/8" NPT or 1/4" NPT ports, suitable for hazardous locations. Various body and coil options available.

1/8" and 1/4" 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. Simple construction... only two moving parts.

When the valve coil is de-energized, the plunger moves upward and disengages the shoulder of the sealing pin allowing the return spring to hold the pin tightly on the orifice seat. When the coil is energized, the plunger accelerates freely before it makes contact with the sealing pin shoulder. Upon contact, it imparts considerable kinetic energy to the pin causing it to lift off the orifice seat against the force of high pressure. For use on air and other non-corrosive gasses, water and oil..
The valve must be mounted 30 degrees of vertical and is for use on air and other non-corrosive gases, water and oil.
