Peter Paul Hazardous Location Valve with Piped Exhaust Model EH23

Contact us to get your personalized offer

PeterPaul dual orifice valves feature a closed body orifice and an open sleeve orifice in the de-energized position, preventing flow between the inlet and cylinder ports while allowing flow between the cylinder and exhaust ports. These valves offer a complete line with a great selection of options and exceptional proven performance. Utilizing the core of the highly successful model H22, Peter Paul Electronics Co., Inc. provides a dual operator valve that offers the same media control as a three-way normally closed valve but with much higher pressure ratings. To function as a three-way normally closed valve, the operators must be alternately energized and de-energized, with pressure at the “IN” port always equal to or greater than the pressure at the “CYL” port. These valves are suitable for air, other non-corrosive gases, 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

When ordering valves or repair packs add voltage and frequency to complete valve number. for examples: valve (EH23JJ19DCCML 120/60) repair pack (2KEH23JJ AC)
