Lug style valves
Lug style Butterfly Valves
1. When the lug butterfly valve is installed with the pipeline, the flanges on both sides are installed with bolts respectively, so that the valve body and the sealing surface of the valve body are not squeezed by the bolts, which is good for the sealing life.
2. The lugs can be easily installed in the discharge position.
3. The connection method of the wafer type has certain defects. When the valve is installed in the pipeline by the bolt, the bolt squeezes the entire butterfly valve body between the flanges on both sides. The bolt is relatively long, and the generated creep is also large, easy to leak, and convex. The lug bolts are relatively short and do not need to pass through the entire valve body.
