Series ELL50 Model ELL52
Very 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 EL52.
• Flame-Proof construction.
• High quality engineering.
