Lift check valves are a type of protective pipeline fittings designed to prevent a change in the direction of the flow of the medium in the process system. Check valves allow the medium to pass in one direction and prevent it from moving in the opposite direction, acting automatically and being a direct-acting valve. With the help of reverse fittings, it is possible to protect various equipment, pipelines, pumps and pressure vessels, as well as significantly limit the flow of the working medium from the system when its section is destroyed.
