Working Principle of Lift Check Valve When the medium passing through the valve from the inlet port, the valve would open if the pressure force of medium exceeds the gravity of disc. However, when the pressure force of backflow medium plus the force of disc's gravity is bigger than the medium force from the inlet side, the valve would close itself to prevent the backflow.
Pound Grade Cast Steel Lift Check valves(Generally flanged connection, but Butt-welding optional) are suitable for use on various kinds of pipeline from Class150 To Class900, PN20 To PN150 to cut off or connect the flowing of medium. By using different material, the valves could be suitable for medium such as water, steam, oil, nitric acid, acetic acid, oxidizing substance, carbamide and etc.
Spring loaded Lift Check valve is in closed position normally. The disc of lift check valve would open owing to the pressure force of inlet side medium. When the medium pressure of inlet side becomes smaller than that of outlet, the spring would push the disc back its seat sealing face to prevent the backflow of medium.
