1. The device is dustproof, waterproof, and resistant to light corrosion, with a protection level ofIP55，IP65(Special Orders)；

2. The torque control mechanism operates reliably, is easy to adjust, and has high torque repeatability accuracy;

3. The travel control mechanism has high adjustment accuracy and repeatability, and can be equipped with various components for opening and closing directions2Only to4Only micro switch;

4. Adopting a semi-automatic manual electric switching mechanism in low gear, the structure is simple, the work is reliable, and the operation is lightweight;

5. Adopting a three-phase asynchronous motor for valve electric devices, with high starting torque and low moment of inertia;

6. Equipped with mechanical valve position indicator.

The butterfly plate of the electric flange butterfly valve is installed in the diameter direction of the pipeline. In the cylindrical passage of the butterfly valve body, the disc-shaped butterfly plate rotates around the axis at an angle of0°~90°Between them, rotate to90°At this time, the valve is fully open.

The electric flange butterfly valve has a simple structure, small size, and light weight, and is composed of only a few parts. And just need to rotate90°It can be quickly opened and closed, with simple operation, and the valve has good fluid control characteristics. When the flange butterfly valve is in the * open position, the thickness of the butterfly plate is the resistance that the medium will have when passing through the valve body, so the pressure drop generated by this valve is very small, and it has good flow control characteristics. Butterfly valves have two sealing types: elastic sealing and metal sealing. Elastic sealing valve, the sealing ring can be embedded on the valve body or attached around the butterfly plate.

Valves with metal seals generally have a longer lifespan than those with elastic seals, but it is difficult to achieve * sealing. Metal seals can adapt to higher operating temperatures, while elastic seals have the drawback of being limited by temperature.

If butterfly valves are required for flow control, the main thing is to choose them correctly The size and type of the valve. The structural principle of butterfly valves is particularly suitable for making large-diameter valves. Butterfly valves are not only widely used in general industries such as petroleum, gas, chemical, and water treatment, but also in the cooling water system of thermal power plants.
