Swing wafer check valves can also be used on pipelines that supply supply to auxiliary systems where the pressure may rise above the pressure of the main system. Check valves can be applied to pipelines with various media depending on their materials. When the check valve is installed on the pipeline, it becomes one of the fluid components of the complete pipeline. The opening and closing process of the valve disc is affected by the transient flow state of the system in which it is located; in turn, the closing characteristics of the valve disc are It has an effect on the fluid flow state.
