Also known as a one-way valve or check valve , check valve, its role is to prevent the media back in the pipeline . The bottom valve pump suction check valve also belong to the class . Opening and closing pieces by medium flow and forces to open or close the valve to prevent backflow of the medium is called a check valve .
Also known as a one-way valve or check valve , Dual Plate Check Valve, its role is to prevent the media back in the pipeline . The bottom valve pump suction check valve also belong to the class .
Opening and closing pieces by medium flow and forces to open or close the valve to prevent backflow of the medium is called a check valve . Check valves are automatic valves , mainly for medium -way flow of the pipeline , allowing only medium to flow in one direction , in order to prevent accidents .

Check valve construction, installation:
1 , the installation location , height, and export orientation must meet the design requirements , pay attention to the direction of media flow in the body should be consistent with the direction of the arrow marked , should be firmly connected tightly .
2 Do not check valve in the pipeline to withstand the weight of large non-return valve should be independent of the support , so that the impact of unmanaged system pressure .
Check valve installation precautions top :
1 , the check valve in the pipeline do not bear the weight of so large a Swing Check Valve should be independent of the support , so that the impact of unmanaged system pressure .
2, note the direction of media flow should be consistent with the direction of the arrow on the body when installing ticket .
3 , the vertical lift valve check valve should be installed on a vertical pipe.
4, the level of valve lift check valve should be installed in horizontal pipelines .
