100mm check valve (lift check valve) is a valve widely used in water, oil, gas and other fluids, and it is also a very important automatic valve. 100mm swing check valve is a device that uses the pressure and flow direction of the fluid to touch the valve plate to control the one-way flow of the fluid, so as to ensure that the pipeline will not flow back and flow interrupted. Among them, when the fluid flows through the side port, the valve core moves downward with the flow of the fluid, and the valve flap is automatically closed, thus preventing the backflow of the fluid, thereby ensuring the safety and stability of the pipeline system. The check valve is characterized by simple structure, flexible operation, long service life, good use effect, and has a very wide range of applications.

In a lift check valve, fluid flow in the forward direction creates pressure that lifts the valve element (disc or ball) off its seat, allowing flow. When the flow stops or reverses, gravity or reverse pressure causes the valve element to fall back into place, sealing the valve and preventing backflow.
These valves are used in piping systems where automatic prevention of backflow is essential, such as in water supply, heating and cooling systems, and various industrial applications. Their design is particularly suited for high-pressure services where velocity of flow is high.
Compact design: Suitable for use where space is limited.
Good for high-pressure systems: Effective at preventing backflow in systems with high flow velocities.
Reduced risk of water hammer: Some designs can offer quicker closing times, potentially reducing the risk of water hammer.
