Electric valve actuators using the new series of GT type electric actuators, double acting and single acting (spring return), Enshi dampers, gear, safety and reliability; large diameter valves adopt series AW pneumatic actuator fork formula transmission, reasonable structure, heater valve, output torque, a double-acting and single-acting. 1, gear dual-piston, output torque, small size. 2, the choice of aluminum alloy cylinder material, light weight, beautiful appearance. 3, at the top, bottom installation manual operating mechanism. 4, the rack connector opening angle can be adjusted, the rated flow. 5, the actuator feedback signal indicates the optional charging and various annexes to automate operations. 6, IS05211 standard connection provides easy installation replacement product. 7, both ends of the adjusting screw allows the standard product section at 0 ° and 90 ° adjustable range of ± 4 °. Ensure the accuracy of synchronization with the valve. Air volume control characteristics of the valve (l) off more Yefeng same amount adjusting valve over size with the national standardization ventilation ducts specified rectangular duct size. (2) the air flow control valve leaves off and cis-open in ventilation, air conditioning, air purification system as a regulator. (3) The test measures the, wind valves, air flow control valve of the gas tightness, the relative amount of air leakage around 5% regulation performance. Enshi Wuhan Han Wei Li Yuen damper valve _ _ wind valve provided by the well-being of Equipment Co., Ltd. Wuhan Han Wei Li Yuen. Enshi Wuhan Han Wei Li Yuen damper valve _ _ wind valve is Wuhan Han Wei Li Yuen-being of Equipment Co., Ltd.
