Low Pressure Cast Iron Check Valve

Check valve should be installed in the direction of media flow, common vertical installation and horizontal installation of two ways. If installed vertically, it is necessary to ensure that the valve and the vertical position is horizontal. If installed horizontally, the installation direction should be determined according to the medium flow direction, and ensure that the valve body is parallel to the pipeline axis.

In the installation process, first of all, should check whether the type and specification of the check valve is in line with the piping system requirements. Secondly, it should be cleaned and descaled to ensure that the surface of the valve is clean and smooth. Then, the check valve is positively confirmed to be placed in the piping system, the installation bolts, tightening torque should meet the requirements. Finally, carry out system pressure test to check the switching status and sealing performance of the check valve.

1. do not let the check valve in the pipeline to bear the weight. Large check valves should be independently supported so that they are not affected by the pressure generated by the piping system.

2. the installation should pay attention to the direction of media flow and the direction of the arrow indicated by the valve body.

3. Spring vertical check valves should be installed in vertical pipelines.4、Horizontal swing check valves should be installed in horizontal pipelines.5、Spring vertical check valves should be installed in horizontal pipelines.6、Spring vertical check valves should be installed in vertical pipelines.
