Peter Paul Hazardous Location Valve Model E52

Contact us to get your personalized offer

PeterPaul single orifice valves have an orifice that remains closed in the de-energized position, preventing any flow between the inlet and outlet ports. Additionally, PeterPaul explosion-proof valves are essential in environments with fire or explosion hazards due to the presence of flammable gases, vapors, liquids, combustible dust, or easily ignitable fibers. These hazardous location valves are recommended, and sometimes compulsory, where a high level of explosion protection is necessary.

  • Miniature Hazardous Location valve.
  • Flame-Proof construction.
  • High quality engineering.

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 (E52K8DCCM 120/60) repair pack (5KE52K 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 (OE52KDDCCM 120/60)


Operating Conditions:

  • Media: Air, and other fluids compatible with standard Buna seals. Hot water, steam, gasoline, oils, some hydraulic fluids, and many media require special seal materials. (Series 50 pressure ratings may change due to the viscosity of the liquid.)*
  • Valve Temperature Range:
    • Standard Valves – 0°F (-18°C) to 104°F (40°C) ambient; 0°F (-18°C) to 150°F (65°C) media.
    • Optional Valves – can tolerate much higher or much lower ambient and media temperatures.*
  • Maximum Operating Pressure Differentials: See table above.
  • Burst Pressure: 5,000 PSI
  • Leakage: Bubble tight for standard valves.
