Series 50 EW Model EW52

Encapsulated Hazardous Location
2-Way Normally Closed Valve

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.
• High quality engineering.
