Product Overview

The silencing check valve is suitable for water supply and drainage pipeline. The valve disc is guided by the central axis at both ends of the inlet and outlet. It can be opened and closed flexibly. It can be installed horizontally or vertically. The valve disc is loaded by spring. Its quick closing can effectively eliminate water hammer. It has good sealing performance and no noise. It has the advantages of small volume, light weight, small fluid resistance, fatigue resistance and long life.

Structural characteristics

1. The disc adopts the shape design of "bullet" and the valve body adopts the shape design of "waist drum" to improve the flow direction of the medium and reduce the coefficient of flow resistance
2, the valve USES a short structure, although the head loss is slightly larger than the lifting silent check valve, but small volume, low price
3. Compact structure, non-metallic lubrication sleeve is installed between the guide shaft and the guide frame, and the valve disc can rise and fall flexibly without locking
4, the skeleton rubber seal ring directly embedded in the valve body, to avoid the medium for a long time of direct erosion of the seal ring, the service life is significantly extended, strong and durable
5, the disc opening and closing stroke is short, can effectively prevent the water hammer
6, suitable for water supply and drainage system, high-rise building pipe network, can be installed in the pump outlet, slightly modified structure, can be used as a suction bottom valve, but not for sewage pipe network
