Product Description

Product description

H76H, H76W, H76X clamp butterfly check valve is composed of body, disc, stem and spring and other parts, using the clamp connection. Due to the short closing stroke of the valve disc and the spring loading, the phenomenon of water hammer can be significantly reduced. The valve is mainly suitable for urban, industrial and high-rise building water supply, drainage pipe network. Because its structural length is shorter than the general check valve, it is most suitable for places with installation space limitation.

Product Features

1, small size, light weight, compact structure, easy maintenance
2, valve plate using dual type, in the spring under the elastic force moment can be self-closing 3, because of the fast closing
effect, can prevent the medium backflow
4, body structure length size is small, rigidity is good
5, safe and convenient, can be used for horizontal and vertical two directions installation

Implementation of standards

1, flange connection size: GB/T1724.1-982
, structure length: GB/T12221-1989, ISO5752-82
