consists of the main parts such as the valve body,valve sheet,deflector,clapper valve,bearing spring ,etc.The internal flow adopts the streamline design to minimize the pressure loss.The opening of clapper valve is very short,so that you can quickly turn off and prevent the great sound of water hammer.It has the characteristic of mute close.

This type of valve is mainly used for water supply and drainage,fire fighting and HVAC system.It can be installed at the exit of water pump to prevent backflow and the water hammer damage to pump.
Main technical parameters:
1.Pressure rating:1.0Mpa,1.6Mpa
2.Testing pressure of valve sheet:1.1Mpa,1.76Mpa
3.Pressure test of valve body:1.5Mpa,2.4Mpa
