Electric Flange Butterfly Valve

Short Description:

Electric flange butterfly valve is usually composed of angular stroke electric actuator (0-90 degree partial rotation) and butterfly valve through mechanical connection, after installation and debugging. It is simple in structure, small in volume and light in weight, and consists of only a few parts. The valve can be switched on and off quickly only by rotating 90 degrees. The operation is simple and the valve has good fluid control characteristics.

Electric flange butterfly valve is usually composed of angular stroke electric actuator (0-90 degree partial rotation) and butterfly valve through mechanical connection, after installation and debugging.

The butterfly plate of the butterfly valve is installed in the diameter direction of the pipeline. In the cylindrical passage of the butterfly valve body, the disc butterfly plate rotates around the axis, and the rotation angle is between 0 ~90. When the rotation angle is between 0 ~90, the valve is fully open.

The butterfly valve is simple in structure, small in volume and light in weight, and consists of only a few parts. The valve can be switched on and off quickly only by rotating 90 degrees. The operation is simple and the valve has good fluid control characteristics.

The electric flange butterfly valve is simple in structure, small in volume and light in weight, and consists of only a few parts. The valve can be switched on and off quickly only by rotating 90 degrees. The operation is simple and the valve has good fluid control characteristics. When the flange butterfly valve is in full open position, the butterfly plate thickness is the only resistance when the medium flows through the valve body, so the pressure drop generated by the valve is very small, so it has better flow control characteristics. Butterfly valve has elastic seal and metal seal. Elastic sealing valve, sealing ring can be embedded in the valve body or attached to the butterfly plate.

Valves with metal seals generally have longer service life than those with elastic seals, but it is difficult to achieve complete sealing. Metal seal can adapt to higher working temperature, while elastic seal has the defect of temperature limitation.

If butterfly valve is required to be used as flow control, the main thing is to select the correct size and type of valve. The structure principle of butterfly valve is especially suitable for making large caliber valves. Butterfly valves are not only widely used in petroleum, gas, chemical industry, water treatment and other general industries, but also used in the cooling water system of thermal power plants.

Commonly used butterfly valves are butterfly valves and flange butterfly valves. The clamp butterfly valve is connected between two pipeline flanges by double-head bolts. The flange butterfly valve has flanges on the valve. The flanges at both ends of the valve are connected to the pipeline flanges by bolts.

In the fully open position, the butterfly plate thickness is the only resistance when the medium flows through the valve body, so the pressure drop generated by the valve is very small.
