What is difference between swing check and lift check valve?
Swing check valves and lift check valves are two types of check valves used to prevent backflow in piping systems. The main difference between them lies in the way they operate.
Swing check valves have a disc that swings on a hinge or pivot as the flow of fluid in the pipeline changes direction. When the fluid flows in the correct direction, the disc swings open, allowing the fluid to pass through. When the flow direction changes, the weight of the disc causes it to swing shut, preventing backflow.
Lift check valves, on the other hand, use a disc that moves up and down to control the flow of fluid. When the fluid flows in the correct direction, the disc is lifted up by the fluid, allowing the fluid to pass through. When the flow direction changes, the disc is pushed back down by gravity and/or the pressure of the fluid, sealing the valve and preventing backflow.
Lift Check Valve, available from suppliers in Dammam, excel in minimizing water hammer and ensuring a secure seal. However, their enhanced performance comes with a higher cost and greater maintenance demands due to their intricate construction.
Advantages of lift check valve:
It ensures that fluid flows in only one direction, preventing backflow and protecting equipment from damage.
It is relatively simple to install and can be easily integrated into existing systems.
These valves have few moving parts, which means that they require minimal maintenance.
They are relatively inexpensive and can be easily replaced if they fail.
They ensure the proper flow of fluid which can reduce the energy consumption.
