?
Performance:
1. When installing the lug butterfly valve and the pipeline, the flanges on both sides are installed with bolts, so that the valve body and the sealing surface of the valve body are not squeezed by the bolts, which is beneficial to the seal life.
2. The lug can be easily installed in the unwinding position.
3. There is a certain defect in the connection method of the clip. When the bolt is used to install the valve in the pipeline, the bolt squeezes the entire butterfly valve body between the two flanges. The bolt is relatively long, and the resulting creep is also large, which is easy to leak
?
Application:
It is widely used in petroleum, chemical, metallurgy, hydropower and many other fields
