Series 20 Model EH23

3-WAY NORMALLY CLOSED

A complete line of valves with a great selection of options and exceptional proven performance. Using the heart of the highly successful model H22, Peter Paul Electronics Co., Inc., has a dual operator valve that allows the same media control as a three way normally closed valve but at much higher pressure ratings than previously available. To function as a 3-way normally closed valve, operators must be alternately energized and de-energized. Pressure applied to the "IN" port must always be equal to or greater than the pressure in "CYL" port. Air and other non-corrosive gasses, water and oil.

Made for higher pressure ratings.
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.

Ordering Information:

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