The use of a lift check valve is to prevent back flow 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 off in a normally closed position. Furthermore, a lift check valve’s process is fully automated because it depends on gravity and the pressure of the media to work. When the pressure increases and reaches its optimal rate, the disk will begin to lift off of the seat, allowing flow to pass through the valve. Gravity is a large factor in operating a lift check valve, due to this, the valve must be in a horizontal position when in use.
