Actuator

Working Principle After receiving a standard current or voltage control signal, the electric actuator's internal motor operates, amplifies torque through a reduction mechanism, and drives the output shaft to push the valve stem, generating a corresponding stroke to precisely position the valve's opening and closing degree. The pneumatic actuator relies on compressed air entering the cylinder to drive the piston or diaphragm to produce thrust, and works with a valve positioner to correct stroke deviations, matching the valve opening according to the input pneumatic signal. Both types can receive system commands to adjust the valve status in real time, enabling dynamic regulation and emergency shutoff of pipeline media. Application Fields 1. Chemical Industry: Drives regulating valves in reactor pipelines for precise control of feeding and pressure relief processes. 2. Thermal Heating: Controls the opening and closing of steam pipeline valves and automatic flow regulation. 3. Power Industry: Remote operation of boiler feedwater and flue gas pipeline valves. 4. Water Supply and Drainage: Automated opening, closing, and throttling of pipeline valves in water plant pumping stations. 5. Oil and Gas Transportation: Remote regulation and emergency shutdown of long-distance pipeline valves.
