Brand: Yangzhou Best Specifications: DZW20 DZW Series multi-turn valve actuators are drive electric valve to control the valve opening and closing. Suitable for gate valves, globe valves, throttle valves, diaphragm valves, which can accurately control command action is far from achieving the valve control, centralized control and automatic control of the best drives. This series of products is not only suitable for power plants, can also be used in petrochemical, metallurgy, utilities and so on. Features 1. The device dustproof, waterproof, light corrosion, the protection class IP55, IP65 (special order); 2. torque control body movements, reliable, easy to adjust, high torque repeatability; 3. adjustable stroke control mechanism high accuracy and repeatability, opening and closing to be fitted to each of 2-4 micro-switch; 4. In low gear semi-automatic hand - electric switching mechanism, simple structure, reliable, easy operation; 5. With Valve three-phase asynchronous motor with electrical devices, high starting torque, small rotational inertia; 6. equipped with a mechanical valve position indicator. Technical parameters Ambient temperature -20 ℃ ~ + 60 ℃ Humidity ≤95% (+ 25 ℃ when) non-flammable working environment, explosive and highly corrosive media. Protection class IP55, IP65 (special order). ≤7% torque repeatability repeated position deviation ≤5 ° power three-phase 380V AC ± 10% 50Hz (special requirements can order).
