Wiring Standard for knife gate valve actuator dzw10-dsi power department;
Dzw series multi turn valve electric device is the driving device of the electric valve, which is used to control the opening and closing of the valve. It is suitable for gate valve, stop valve, throttle valve and diaphragm valve. It can accurately control the command action. It is a driving device for remote control, centralized control and automatic control of the valve. This series of products are not only suitable for power stations, but also for petrochemical, metallurgy, public utilities, etc.
Characteristic
1. The device is dust-proof, water-proof and light corrosion proof, and its protection grade is IP55 and IP65 (special order);
2. The torque control mechanism has reliable action, convenient adjustment and high torque repetition accuracy;
3. The stroke control mechanism has high adjustment accuracy and repetition accuracy, and the opening and closing directions can be equipped with two or four microswitches respectively;
4. The semi-automatic hand electric switching mechanism is adopted in the low-speed gear, which is simple in structure, reliable in operation and light in operation;
5. Adopt three-phase asynchronous motor for valve electric device, with large starting torque and small moment of inertia;
6. Equipped with mechanical valve position indicator.
