A lift-check valve is a check valve in which the disc, sometimes called a lift, can be lifted off its seat by higher pressure of inlet or upstream fluid to allow flow to the outlet or downstream side. A guide keeps the motion of the disc on a vertical line, so the valve can later reseat properly.
The use of a lift check valve is to prevent backflow into a stream. The valve is used mainly in water applications because of its design. The pressure of the media is what is used to open the lift check valve, which starts in a normally closed (NC) position.
