Horizontal lift check valves are used primarily for air, gas, and steam services whilst swing check valves are most suitable for water and other liquids. For air, gas, and low-pressure applications, especially where bubble-tight closure is required, a valve with the rubber-faced disc is necessary.

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.
