Series ELL50 >> Model ELL53 Very Low Watt Hazardous Location —
3-Way Normally Closed Valve — Exhaust to Atmosphere
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 uses less power than EL53. • Flame-Proof construction.
• High quality engineering.
Body: Stainless Steel (Std.)
Internal Components: Stainless Steel
Elastomers: Nitrile (Buna) (Std.). Many other elastomers available.*
Orifice Diameter: See table on proceeding page.
Porting: 1/8′′ NPT (Std.)
Housing: Flame-Proof construction with 1/2′′ NPT conduit
Listings: Valves are UL listed and CSA certified for Hazardous Locations — Class I, Div 1, Group C and D – Class II, Div 1, Groups E, F, and G; Div 2, Groups C, D, E, F, and G
Life Expectancy: Millions of cycles, depending on application, lubrication, etc.
Valve Weight: 0.65 lbs
Repair Kits: See table on proceeding page.
Options: Alternate Port Locations, Metering, Alternate Elastomers, All Stainless Steel Construction*
