Product Description
Butterfly check valve
H76X/H76H/H76W butterfly check valves are used for pure pipelines and industrial, environmental protection, water treatment, water supply and drainage pipelines of high-rise buildings to prevent reverse flow of media. The check valve adopts a pair of clamps, the butterfly plate is two semicircles, and the spring is forced to reset. The sealing surface can be surfacing wear-resistant material or lining rubber for the body. It has a wide range of applications and reliable sealing.
