Swing Check Valve SWD-V113 For Water Pump

1.Swing Check valve installation

Swing Check valve, also known as check valves, is one of the indispensable products in piping systems.
Its role is to prevent the media from flowing back and prevent the media from flowing backward.
Swing Check valve, installation note:
1. PVC special glue must be used.
2. The direction of the water flow should be consistent with the direction of the arrow on the valve.

3. Usually installed at the bottom of the pump to prevent damage to the pump impeller due to backflow of power.

2.The difference between the two check valves

1. The ball-type check valve rebounds by the spring. When there is no water flowing in the pipe, the ball is sealed and the water is prevented from flowing backward due to spring rebound.
2. The flap type check valve relies on its own gravity. When there is no pressure in the pipeline, the baffle is sealed by its own gravity to prevent backflow.
