HAZARDOUS LOCATION VALVES
Series E50 >> Model E51
Hazardous Location — 2-Way Normally Open 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 protec- tion from explosion is required.
Note: This valve also available as an operator. Refer to following page.
OPERATING CONDITIONS
Media: Air, and other fluids compatible with standard Buna seals. Hot water, steam, gasoline, oils, some hydraulic fluids, and many media require special seal materials. (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: 5000 PSI
Leakage: Bubble tight for standard valves.
Vacuum: To 5 Microns*
