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 Coolant and Detergent

These valves 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—Fluoroelastomer Seal

Image of Product. Front orientation. Contains Annotated. Solenoid On/Off Valves. Solenoid On/Off Valves for Coolant and Detergent, Brass Body with Wire Lead Connection—Fluoroelastomer Seal.

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

Fail-Open Valve—Fail open valves are open unless actuated.

Zero Pressure Drop Valve—Zero pressure drop valves don’t require a minimum pressure drop between the inlet and outlet for operation.

IP65 Enclosure Rating—Valves rated IP65 and/or NEMA 4 resist washdowns, splashing water, and dust.

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.

Enclosure Rating—Enclosure ratings only apply to the valve’s enclosure.
