    To automatically start and stop flow faster 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 reduce wear. A visual flow indicator on the top of the actuator shows whether the valve is open or closed. The manual override allows you to operate the valve during power outages. Valves meet NSF/ANSI 61 for use with drinking water.
    All valves are lug style; their hole pattern matches ANSI flanges of the same pipe size. They can be sandwiched between two flanges, or bolt them directly to a single flange for servicing one end of the pipeline without depressurizing the other side.
    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.
    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.

    An aluminum body provides strength and durability at half the weight of other metal flanged flow-adjustment valves. These valves bolt to flanges for adjusting and regulating flow in flanged pipelines. Fix the lockable lever handle in place using a padlock (not included) with a shackle diameter up to 5/16”. Valves are wafer style, so they must be sandwiched between two flanges; all have unthreaded holes or tabs to help align the valve between the flanges.
    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.

    Flanged Motor-Actuated On/Off Valves

    Automatically start and stop flow in flanged pipelines with these valves that operate on electricity. All are fail in place; upon loss of power, the valve will remain in its current position.
    The actuator is directly mounted to the valve body to minimize movement and reduce wear. A visual flow indicator on the top of the actuator shows whether the valve is open or closed. Two single pole, double throw (SPDT) auxiliary switches allow you to connect these valves to temperature-monitoring equipment, programmable logic controllers, or conveyor sirens. The internal heater automatically turns on when the valve is actuated to prevent motor damage caused by condensation buildup. Valves meet NSF/ANSI Standard 61 for use with drinking water.
    All valves are lug style; their hole pattern matches ANSI flanges of the same pipe size. They can be sandwiched between two flanges, or bolt them directly to a single flange for servicing one end of the pipeline without depressurizing the other side.
