Series 50 EW Model EW51

2-WAY NORMALLY OPEN

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.

Ordering Information:

When ordering valves or repair packs add voltage and frequency to complete valve number. for examples: valve (EW51J8XCCP 120/60) repair pack (KEW51J AC)

When ordering operators add the letter “O” to the front of the valve number, replace body port number with the letter “D”: example: operator (OEW51J8DCCP 120/60)

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.)*
