Series EL 50 Model EL52

2-WAY NORMALLY CLOSED

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 E52.
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 (EL52H8DCCM 120/60) repair pack (5KEL52H 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 (OEL52HDDCCM 120/60)
