HAZARDOUS LOCATION VALVES
Series E50 >> Model E56
Hazardous Location — 3-Way Multi-Purpose 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.
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*
ELECTRICAL CHARACTERISTICS
Coil Voltage: 6.0 to 575V AC 60 HZ. and 5.4 to 515V AC 50 HZ. — 3.0 to 300V DC. Nominal Power: AC — 5.6 Watts DC — 7.2 Watts
Coil Construction: Molded Class F with third wire ground (Std.), Class H or Potted (Opt.) Typical Response Time on Air: 4 – 16 Milliseconds
Operating Speed: Up to 600 CPM
Duty Cycle: Continuous
