About Actuated On/Off Valves

For Use With: Water, Air, Argon, Helium, Neon, Xenon, Krypton
Seal Material: Buna-N Rubber

These top-of-the-line valves are comparable to Asco Red Hat 8210G Series and Parker Gold Ring 23C Series. 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.

Normally closed valves are closed unless actuated. Normally open valves are open unless actuated.

Zero pressure drop valves don’t require a minimum pressure drop between the inlet and outlet for operation. 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 valves resist washdowns, splashing water, corrosive liquid, and dust.

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.

Premium Compact Solenoid On/Off Valves

For Use With: Water, Oil, Air, Argon, Helium, Neon, Xenon, Krypton
Seal Material: Buna-N Rubber
Environmental Rating: NEMA 3S, NEMA 4X
Specifications Met: UL Listed, CSA-US Certified, CSA Certified, CE Marked

Normally closed valves are closed unless actuated. Normally open valves are open unless actuated.

304 stainless steel valves are more corrosion resistant than 430 stainless steel valves.

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.
