Clip check valve H76H
It is used for pure pipeline and industrial, environmental protection, water treatment, high-rise building water supply and drainage pipeline, to prevent the reverse flow of media. The check valve adopts the clamp type, the butterfly plate is two semicircle, and the spring is forced to reset. The sealing surface can be used as the wear-resistant material or rubber lining for the body surfacing. The use range is wide and the seal is reliable.
Characteristic
1. Small size, light weight, compact structure and convenient maintenance.
2. The valve plate adopts dual mode, and can be closed automatically under the elastic force of the spring.
3. The reflux of medium can be prevented because of fast closing.
4. The length and size of the valve body is small, and the rigidity is good.
5. Safe and convenient. It can be installed in two directions.
Standard of execution
1, flange connection size: GB/T1724.1-98
2. Structure length: GB/T12221-1989, ISO5752-82
