Electric Flange Butterfly Valves

Electric flange butterfly valves are usually composed of an angle stroke electric actuator (with a partial rotation of 0-90 °) and a butterfly valve, which are mechanically connected and installed and debugged together.
The butterfly plate of the butterfly valve is installed in the diameter direction of the pipeline. In the cylindrical channel of the butterfly valve body, the disc shaped butterfly plate rotates around the axis, with a rotation angle between 0 ° and 90 °. When rotated to 90 °, the valve is fully open.
The butterfly valve has a simple structure, small size, and light weight, and is only composed of a few parts. Moreover, the valve can be quickly opened and closed by rotating it 90 °, with simple operation and excellent fluid control characteristics.

Moreover, the valve can be quickly opened and closed by rotating it 90 °, with simple operation and excellent fluid control characteristics. When the flange butterfly valve is in the fully open position, the thickness of the butterfly plate is the only resistance when the medium flows through the valve body, so the pressure drop generated through the valve is very small, so it has good flow control characteristics. Butterfly valves have two types of sealing: elastic sealing and metal sealing. Elastic sealing valve, the sealing ring can be embedded on the valve body or attached to the periphery of the butterfly plate.
Valves with metal seals generally have a longer lifespan than valves with elastic seals, but it is difficult to achieve complete sealing. Metal seals can adapt to higher working temperatures, while elastic seals have temperature limitations.
If a butterfly valve is required for flow control, the main thing is to choose the correct size and type of 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 cooling water systems of thermal power plants.
There are two commonly used butterfly valves: wafer type butterfly valve and flange type butterfly valve. A wafer type butterfly valve is a valve that is connected between two pipeline flanges using double headed bolts. A flange type butterfly valve is a valve with a flange, and the flanges at both ends of the valve are connected to the pipeline flange using bolts.
