Peter Paul Hazardous Location Valve Model EL51

Contact us to get your personalized offer

PeterPaul single orifice valves feature a closed orifice in the 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 or sometimes compulsory where a high level of explosion protection is required.

  • Miniature Hazardous Location valve using even less power than an E51.
  • Flame-Proof construction.
  • High quality engineering.

Ordering Information:

When ordering valves or repair packs add voltage and frequency to complete valve number. for examples: valve (EL51H8XCCM 120/60) repair pack (5KEL51H 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 (OEL51HDDCCM 120/60)
