Principle:
  • A swing check valve consists of a flap or disc of the same diameter as the pipe bore, which hangs down in the flow path.
  • With flow in the forwards direction, the pressure of the fluid forces the disc to hinge upwards, allowing flow through the valve.
  • Reverse flow will cause the disc to shut against the seat and stop the fluid going back down the pipe.
  • In the absence of flow, the weight of the flap is responsible for the closure of the valve; however, in some cases, closure may be assisted by the use of a weighted lever.
