1. Check valves in pipelines cannot bear weight, especially large check valves should be installed independently and not affected by the pressure generated by the system.

2. The direction marked on the valve body should be the same as the direction of medium flow

3. The medium passing through the pipeline should not contain hard particles to avoid damaging the sealing surface, and should not be used for medium containing solid particles and high viscosity. 4. The installation position of swing check valves should be noted.
