About Actuated On/Off Valves

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.

Bronze Body

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.

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.

Threaded Air-Driven Diverting Valves

To divert flow between ports more quickly than motor-driven valves, these operate on compressed air. You must control the air to the actuator using either the included electric pilot valve or a manual on/off valve (not included). Valves don’t require a minimum pressure drop between the inlet and outlet for operation. The actuator is directly mounted to the valve body to minimize movement and wear. Valves are standard port, so they slightly restrict flow.

Air-to-Divert/Air-to-Return—Air-to-divert/air-to-return valves require air pressure to divert flow to the right-port outlet and air pressure to return flow to the left-port outlet.

Air-to-Divert/Spring Return—Air-to-divert/spring-return valves require air pressure to divert flow to the right-port outlet. They automatically return flow to the left-port outlet when the air turns off to ensure the valve only diverts flow to the right port when air is on.

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.

Air-Operated Air On/Off Valves

Also known as blocking valves, these valves are activated by an air signal to turn equipment on and off. They allow airflow when an air signal is applied to the air pilot. When the air supply is removed, the valve closes, trapping air in the system.

Flow Coefficient (Cv)—Flow coefficient (Cv) is a measurement that indicates how much airflow can pass through a valve. When selecting between valves with the same port size, choose the valve with the higher flow coefficient to ensure it provides enough airflow to operate your system.

High-Flow Air-Driven On/Off Valves

Also known as actuated ball valves, these provide higher flow rates than other air-driven valves. They operate on compressed air to automatically start and stop flow faster than motor-driven valves. You must control the air to the actuator using either the included electric pilot valve or a manual on/off valve (not included).

Direct-mount actuators are directly attached to the valve body to minimize movement and reduce wear.

NEMA 4 valves resist washdowns, splashing water, and dust.

IP66 valves resist dust and high-pressure jets of water.

Full Port—Full-port valves do not restrict flow.

With Visual Flow Indicator—Valves with a visual flow indicator on the top of the actuator show whether the valve is open or closed.

Single Acting—Single-acting actuators only require air pressure to open the valve; they automatically spring closed when the air turns off. These valves are fail closed unless actuated.

Double Acting—Double-acting actuators require air pressure to open and close the valve. Once actuated, these valves remain actuated until air pressure is applied, so they do not have a valve starting position.

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.

Made-to-Order Air-Operated Air-Exhaust Control Valves

When these valves receive an air signal, they quickly dump exhaust air to the atmosphere without routing it back through a directional control valve to speed up the movement of equipment. They're often used with air compressors that require continuous operation. A muffler reduces exhaust noise. Also known as quick exhaust valves.

To Order: Specify minimum pressure and maximum pressure from the ranges listed. The difference between the minimum pressure and maximum pressure must be at least 10 psi, but no more than 30 psi.

Compact Severe-Duty Air-Driven On/Off Valves

Less than half the height of standard severe-duty valves, these fit in small spaces and low-clearance pipelines. They have a diaphragm that can handle dirty liquid, slurries, and abrasive media without damage. All 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 require a minimum pressure drop between the inlet and the outlet for operation; the upstream pressure must be greater than the downstream pressure.

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 directly mounted to the valve body to minimize movement and reduce wear.

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

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