Series 20 Model EH22

2-WAY NORMALLY CLOSED

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.

Precision stainless steel, free floating plunger.
Kel-F pin sealing element.
Orifice guides the sealing pin for near perfect alignment.
Simple construction...only two moving parts.
Explosion proof construction.

# DELRIN PIN SEALING ELEMENT STANDARD THIS SIZE ORIFICE. (KEL-F OPTIONAL)

Ordering Information:

Seal Material: Replace ∆ with desired code - Blank = Nitrile (Buna) S = Low Temp Buna. N = FKM* E = Neoprene A = EPDM

When ordering valves or repair packs add voltage and frequency to complete valve number. for examples: valve (EH22J7DCCM 120/60) repair pack (2KEH22J AC)

When ordering operators add the letter “O” to the front of the valve number, replace body port number with the letter “D”: example: operator (OEH22JDDCCM 120/60)
