Precautions for one-way valves
When installing the check valve, special attention should be paid to the direction of medium flow. The normal flow direction of the medium is consistent with the direction of the arrow indicated on the valve body, otherwise the normal flow of the medium will be cut off. The bottom valve should be installed at the bottom of the water pump suction pipe.
When the check valve is closed, water hammer pressure will be generated in the pipeline. In severe cases, it will cause damage to the valve, pipeline or equipment, especially for large-mouth pipelines or high-pressure pipelines, so it should cause stoppage. Return valve users should pay high attention to this.
Check valves are only one-way opening and closing valves that prevent the backflow of fluid media on various pipelines or equipment.
