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.

Hazardous Location valves are recommended, or in some cases compulsory, where a high level of protection from explosion is required.
Explosion Proof
The flagship valve initially created for the fluid power industry.
Heavy duty and made of stainless steel.
A real workhorse with proven performance.
It has the greatest amount of options available of all the valves.
Wide range of orifice sizes from 1/32" to 1/4".

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 example: valve (E22N9DCCM 120/60) repair pack (2KE22K 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 (OE22NDDCCM 120/60)
