Peter Paul Hazardous Location Valve Model N72

Contact us to get your personalized offer

PeterPaul single orifice valves in which the orifice is closed in the de-energized position and no flow can exist between the inlet and outlet ports.
The N70 line PeterPaul Hazardous location valves are UL listed and Certified for Non-Incendive Hazardous Locations — Class I, Div 2, Groups A,B,C and D – Class II, Div 2, Groups E,F and G – T3C Temperature rating.

  • Largest direct acting (non-piloted) valve we manufacture.
  • Large orifice.
  • High flow.
  • Will operate effectively at very low pressures or vacuum.

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 (N72R9DCP 120/60) repair pack (KN72RDD 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 (ON72RDDCP 120/60)

 

Operating Conditions:

  • Media: Air, water, and other fluids compatible with standard Buna seals. Hot water, steam, gasoline, and many oils require special seal materials. (Series 70 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: 4,000 PSI
  • Leakage: Bubble tight for standard valves.
  • Vacuum: To 5 Microns*
