About Actuated On/Off Valves

Choose the right automatic on/off valve based on power source, pressure, and flow rate.

Solenoid On/Off Valves for Steam

These valves are designed to withstand the high temperatures and pressures in steam service applications. They operate on electricity to automatically start and stop flow. The actuator is directly mounted to the valve body to minimize movement and reduce wear.

Brass Body with Wire Lead Connection—EPDM Seal

Fail-Closed Valve—Fail closed valves are closed unless actuated.

Pressure Drop Assisted Valve—Pressure drop assisted valves require a minimum pressure drop between the inlet and the outlet for operation; the upstream pressure must be greater than the downstream pressure.

NEMA 4X Enclosure Rating—NEMA 4X valves resist washdowns, splashing water, corrosive liquid, and dust.

Flow Coefficient (Cv)—Flow coefficient (Cv) is the amount of water (in gallons per minute) at 60° F that will flow through a fully open valve with a difference of 1 psi between the inlet and the outlet.
