    About Actuated On/Off Valves
    industrial info icon

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

    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.

    316 stainless steel valves are more corrosion resistant than brass and bronze valves.
    Fail-Closed Valve—Fail closed valves are closed unless actuated.
    Pressure Drop Assisted—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.
    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.

    316 stainless steel valves are more corrosion resistant than brass and bronze valves.
    Valves with a visual flow indicator on the top of the actuator show whether the valve is open or closed.
    Fail-Closed Valve—Fail closed valves are closed unless actuated.
    Fail-Open Valve—Fail open valves are open unless actuated.
    Zero Pressure Drop—Zero pressure drop valves don’t require a minimum pressure drop between the inlet and outlet for operation.
    IP65 Enclosure Rating—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.
    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.

    Severe-Duty Air-Driven On/Off Valves

    Image of Product. Back orientation. Contains Annotated. Air-Actuated On/Off Valves. Severe-Duty Air-Driven On/Off Valves.
    Also known as diaphragm valves, these have a diaphragm that can handle dirty liquid, slurries, and abrasive media without damage. 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 (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. All meet ANSI/FCI 70-2 Class IV for tight shutoff and have a leakage rate of less than 0.01%.
    All 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 secured to the valve body with a bracket for easy disassembly, maintenance, and repair. These valves are fail closed unless actuated.
    316 Stainless Steel Body—316 stainless steel valves are more corrosion resistant than bronze valves.
    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.

    Compact Versa-Mount Air-Driven On/Off Valves

    Image of Product. Front orientation. Contains Annotated. Air-Actuated On/Off Valves. Compact Versa-Mount Air-Driven On/Off Valves.
    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 fail 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)—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.
