DZW series multi turn valve electric device is the driving device of electric valve, which can control the opening and closing of valve. For the valve, the cut-off valve, throttle valve, diaphragm valve, it can accurately control commands, the valve is to achieve remote control, centralized control and automatic control of the driving device is preferred. This series of products can be used not only for power plants, but also for petrochemical, metallurgical, public utilities and so on.
Characteristic
1. the device is dustproof, waterproof and light corrosion resistant, and its protection grade is IP55, IP65 (special order);
2. the torque control mechanism is reliable, easy to adjust, high torque repetition accuracy;
The 3. stroke control mechanism has high adjustment accuracy and repeatability, and the opening and closing can be fitted with 2 to 4 micro switches;
4. the semi-automatic hand electric switching mechanism is used in the low speed gear, the structure is simple, the operation is reliable, and the operation is light;
5. uses the valve electric device uses the three-phase asynchronous motor, the start torque is big, the rotational inertia is small;
6. equipped with mechanical valve position indicator.
