Series EL 50 Model EL52

Low Wattage Hazardous Location
2-Way Normally Closed Valve

Peter Paul 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.

OPERATING CONDITIONS

Media: Air and other common gases and common refrigerants except ammonia, city gas supplies by public utilities, Nos. 1 and 2 fuel oils, oils having viscosities not more than 40, SU at 100° F, steam, some hydraulic and water or other aqueous non-flammable liquids. Some media require special seal material. (Series 50 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.*
