The working principle of butterfly valve

Butterfly valve is based on the stem rotation, while driving the movement of the valve plate to open and close a state of the valve. In the cylindrical channel of the butterfly valve body, the disc shaped valve plate revolves around the axis of the butterfly valve, mainly rotating the valve plate 90 degrees to play a role in flow control.

When the butterfly valve plate reaches 90 degrees, the valve is in full open state, at the same time can change the position of the butterfly valve plate Angle to adjust the medium flow, generally installed in the diameter of the pipeline direction. The butterfly valve and the stem themselves have no locking capacity. In order to effectively regulate the flow, it is necessary to install the turbine reducer. The butterfly valve pretending to be a turbine reducer not only enables the butterfly valve to have self-locking capacity, but also changes the operating performance of the butterfly valve and more accurately regulates the flow of medium.
