Vertical Lift Check Valve

Product description

  • Check valve is an automatic valve, also known as check valve, one-way valve, return valve or isolation valve.
  • The medium flows in from the inlet end (lower side) and flows out from the outlet end (upper side). When the inlet pressure is greater than the disc weight and its flow resistance, the valve is opened. On the contrary, the valve will be closed when the medium flows back.

Vertical lift check valve

1.Vertical lift check valve refers to the valve that automatically opens and closes the valve disc depending on the flow of the medium itself to prevent the backflow of the medium.

2.The function of this type of valve is to allow the medium to flow in only one direction and prevent the flow in the opposite direction. Usually, this valve works automatically. Under the action of fluid pressure flowing in one direction, the valve disc opens; When the fluid flows in the opposite direction, the fluid pressure and the self weight of the valve disc act on the valve seat, so as to cut off the flow.
