Series 20 Model EH23
Hazardous Location High Pressure
3-Way Normally Closed Valve (exhaust to atmosphere)
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 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.
