Rotary actuator A812 series

hydraulicpneumaticsingle-acting

The actuator is a multi-spring pneumatic diaphragm actuator that controls the opening and closing of straight stroke control valves, and can be used with our A100 series and other straight stroke valves. Features Convenient model selection and application, because the specifi cation and model of the actuator can be confi gured according to the caliber and pressure rating of the control valve Compact structure design, small size, light weight, high accuracy, large thrust and suitable for extensive use in various scene Unique diaphragm pressing structure, ensuring reasonable compressing of the diaphragm and facilitating maintenance and replacement of the diaphragm Top-mounted, side-mounted, hydraulic and other types of manual mechanisms to meet various user demands Convenient and quick connection with solenoid valve, stroke switch, lock-up valve, pneumatic control valve, relay, valve position transmitter and other accessories Modular combined structure, bringing about strong universality of parts. Fewer spare parts needed, because direct and reverse actions can be realized by adjusting the direction of the diaphragm head and easy maintenance Unique push rod sealing design structure, which can prevent corrosion caused by the external environment, enhance the sealing effect, and have a longer service life Smooth and aesthetic plastic-sprayed outer surface of the diaphragm cover with strong corrosion resistance Compatible with integrated and easy-to-calibrate AVP-400 series intelligent valve positioner and YT-1000 series electro-pneumatic valve positioner, as well as other types of valve positioners
