For faster actuation than motor-driven valves, these operate on compressed air. Integrate them into PLC systems for automatic control over the valve position based on system conditions. The actuator has a built-in electric pilot valve that controls the air supply to the valve. Set how much to open the valve using the programmable controller on the actuator. They can accept both 4-20 mA current and 0-10 DC voltage. Valves don’t require a minimum pressure drop for operation.

All have a single-acting actuator that only requires air pressure to open the valve; it automatically springs closed when the air turns off. Valves are normally closed unless actuated. The actuator is directly mounted to the valve body to minimize movement and reduce wear. Valve body is stainless steel for good corrosion resistance. All meet NEMA 4X, IP65, and IP67 for resistance to 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.
