HAZARDOUS LOCATION VALVES
Series 50 ELW >> Model ELW53 Encapsulated Low Wattage Hazardous Location —
3-Way Normally Closed Valve — Piped Exhaust
A UL and CSA listed, low watt, miniature hazardous location valve with minimal space and energy requirements in volatile environments. Air and other fluids compatible with standard Buna seals. Hot water, steam, gasoline, oils, some hydraulic fluids, and many other media require special seal materials.
• Smallest hazardous location solenoid valve.
• Best ambient and high temperature ratings on the market. • NEMA 4 rating is standard with encapsulated coil.
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 140°F (60°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*
