Easy-maintenance Air Actuated 3-pc Stainless Ball Valve Double Acting


3-PC type Air-Driven On/Off Valves-we provide solenoid valve, air filter and limit switch as well.

The three-piece bolted body comes apart for access to internal components without unthreading pipe connections and removing the valve from your line. Their ball-valve design allows these valves to achieve higher flow rates than other air-driven valves. They operate on compressed air to automatically start and stop flow. You must control the air to the actuator using either the included electric pilot valve or a manual on/off valve (not included). These valves require a minimum pressure drop between the inlet and the outlet for operation; the upstream pressure must be greater than the downstream pressure. Body is 316 stainless steel for excellent corrosion resistance. All valves have a visual flow indicator on the top of the actuator that shows whether the valve is open or closed.

Single-acting(spring return) actuators only require air pressure to open the valve; they automatically spring closed when the air turns off. These valves are normally closed unless actuated.

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