The lug style butterfly valve . They have the advantage of connecting the two ends of the pipe with a short bottom. The "-ear" here refers to bolting the valve to the pipe flanges at both ends,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°-90°. When the rotation reaches 90°, the valve is in a fully open state.

1. When the lug style butterfly valve is connected to the pipeline, the flange is installed with bolts in each eye, so that the valve

The body and the valve body sealing surface are not subject to strong extrusion, which is beneficial to the sealing life.

2. The lug type can be easily installed at the discharge position

3. The lug type bolts are relatively short and do not need to pass through the entire valve body. It avoids the defects that the valve bolts are relatively long, causing large creep and easy leakage.

Lug style butterfly valves are usually composed of metal such as ductile iron or steel. They feature threaded tapped lugs positioned on the valve flanges for bolt connections. Lug style butterfly valves are suitable for end-of-line service 。
