   HAZARDOUS LOCATION VALVES
   Note: This valve also available as an operator. Refer to following page.
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.*
Maximum Operating Pressure Differentials: See table on proceeding page.
Burst Pressure: 4000 PSI
Leakage: Bubble tight for standard valves.
Vacuum: To 5 Microns*

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 E53. • Flame-Proof construction.
                                                                                                                                                                                                   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.
