It's the wafer type valves, but the designed U type flanges facilitate the pipeline centering The butterfly plate of the U type 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, and the rotation angle is between 0° and 90°. When the rotation reaches 90°, the valve is fully opened.
U-type butterfly valve adopts mounted structure, which reduces the connection bolts of the body under the condition of high pressure and large diameter, enhances the reliability of the valve, and overcomes the influence of system weight on the normal operation of the valve. It can be opened and closed quickly.
