a. The valve disc adopts a “bullet head” shape design, and the valve body adopts a “waist drum” shape design to improve the medium flow direction and reduce the flow resistance coefficient.
b. The valve adopts a short structure. Although the head loss is slightly larger than that of the lift silent check valve, it is small in size and cheap in price.
c. The structure is compact, and a non-metal lubricating sleeve is installed between the guide shaft and the guide frame. The valve disc can be lifted and lowered flexibly without locking.
d. The skeleton rubber sealing ring is directly embedded on the valve body, which avoids direct erosion of the sealing ring by the medium for a long time, significantly extends the service life, and is strong and durable.
e. The valve disc has a short opening and closing stroke, which can effectively prevent water hammer.
f. It is suitable for water supply and drainage systems and high-rise building pipe networks. It can be installed at the outlet of the pump. With slight modifications to the structure, it can be used as a water suction bottom valve, but it is not suitable for sewage pipe networks.
Steel body flange vertical silencer check valve
The valve is made up of body, disc and spring etc. It is applicable to water supply and drainage pipeline, the disc is guided by centre axis of inlet and outlet, loaded by spring. It can close rapidly reducing water hammer pressure and is free to closing without noise. The valve can be fixed horizontally or vertically. It also has the characteristic of small volume, light weight, little flow resistance, enducing fatigue, long life-span.
