Check Valves Flanged End are used mostly to prevent the medium from flowing back in the piping system. Check valves only allow the medium to flow in one direction, and when the medium flows in, the disc of check valves swings off the seat to allow forward flow and when the flow stops, the disc swings back onto the seat to block reverse flow.
