2-PC type 1000WOG Air-Driven On/Off Va es-we provide solenoid va e, air filter and positioner as well.
1. SS304 or SS316L va e body
2. PTFE sealing
3. 1/4"-4" or DN8 to DN200
Their ball-va e design allows these va es to achieve higher flow rates than other air-driven va es. 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 va e or a manual on/off va e (not included). These va es 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 or 304 stainless steel for excellent corrosion resistance. All va es have a visual flow indicator on the top of the actuator that shows whether the va e is open or closed.
Single-acting(spring return) actuators only require air pressure to open the va e; they automatically spring closed when the air turns off. These va es are normally closed unless actuated. Double-acting actuators require air pressure to open and close the va e. Once actuated, these va es remain actuated until air pressure is applied to close them, so they do not have a va e starting position.
