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.

U type butterfly valve is different from wafer or lug type butterfly valve, because it is flange connection and shorter face to face length.
Small in size, light in weight, easy installation, and maintenance.
Short pattern with flanges drilling holes.
ISO 5211 mounting pad compatible for various types of actuators;
Long service life, standing the test of tens of thousands of opening/closing operations.
Compact and lightweight, easy to disassemble and repair, and can be installed at any position.
The structure is simple and compact, the operating torque is small, and the 90° rotation starts quickly.
The flow characteristics tend to be straight and the adjustment performance is good.
The connection between the disc and the valve stem adopts a pinless structure, which overcomes the possibility of internal leakage.
