The butterfly disc of the clamp butterfly valve is installed in the diameter direction of the pipe.
In the cylindrical channel of the butterfly valve body, the disc shaped butterfly plate rotates around the axis, the rotation Angle is between 0°-90°, rotate to 90°, the valve brand is fully open.
This valve is generally installed horizontally.
The butterfly valve is simple in structure, small in size and light in weight, and consists of only a few parts. And only need to rotate 90° can quickly open and close, simple operation, at the same time, the valve has good fluid control characteristics.
Butterfly valve 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 by the valve is small, so it has better flow control characteristics.
Butterfly valve has two types of seal and metal seal. rubber resilient seal valve, sealing ring can be mounted on the body or attached to the butterfly plate around.
