Series EL 50 Model EL51

2-WAY NORMALLY OPEN

PeterPaul explosion proof valves are used where fire or explosion hazards exist due to the presence of flammable gases or vapors, flammable liquids, combustible dust, or easily ignitable fibers. Hazardous Location valves are recommended, or in some cases compulsory, where a high level of protection from explosion is required.

Miniature Hazardous Location valves using even less power than an E51.
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 (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)
