Series 50 EW Model EW55
Encapsulated Hazardous Location
3-Way Directional Control Valve
A UL 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.
• Serves as a general purpose valve for pneumatic and hydraulic conditions.
• High quality engineering.
