Peter Paul Hazardous Location Valve Model ELL52

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.

Available on backorder



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 (ELL52G8DCCM 120/60) repair pack (5KELL52G 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 (OELL52GDDCC 120/60)
