About Actuated On/Off Valves

Versa-Mount Air-Driven On/Off Valves

Also known as piston valves, these have a compact, lightweight actuator and an angular body designed for installation in any mounting orientation. They operate on compressed air to automatically start and stop flow. You must control the air to the actuator using either an electric pilot valve (included when listed) or a manual on/off valve (not included).

Valves have a single-acting actuator that only requires air pressure to actuate the valve; they automatically return to the valve starting position when the air turns off. 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.

316 stainless steel valves are more corrosion resistant than brass and bronze valves.

IP65 valves resist low-pressure jets of water and dust. They include an electric pilot valve to turn the air supply on and off. All have a manual override for operating the valve during power outages.

Valves with a visual flow indicator on the top of the actuator show whether the valve is open or closed.

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.

Compact Versa-Mount Air-Driven On/Off Valves

Valve Type: Piston
For Use With: Water, Air, Argon, Helium, Neon, Oxygen, Xenon, Krypton
Seal Material : PTFE Plastic

About half the height of our other versa-mount valves, these fit in tight spots. All have a compact, lightweight actuator and an angular body designed for installation in any mounting orientation. They operate on compressed air to automatically start and stop flow. You must control the air supply to the valve using either electricity or compressed air. You must control the air to the actuator using either an electric pilot valve (not included) or a manual on/off valve (not included). Valves don’t require a minimum pressure drop between the inlet and outlet for operation.

They have a single-acting actuator that only requires air pressure to open the valve; they automatically spring closed when the air turns off. All valves are normally closed unless actuated. The actuator is directly mounted to the valve body to minimize movement and reduce wear. Body is 316 stainless steel for excellent corrosion resistance.

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.

With a chemical-resistant fluoroelastomer seal and no metal parts to corrode, these valves are often used in chemical-processing and water-treatment applications.
