Cast Steel Lifting Flange Check Valve

The operation of cast steel lifting flange check valve is based on the principle of fluid dynamics. When the medium flows forward, the fluid pressure pushes the valve disc to move upward along the axis of the valve seat channel, the valve disc opens, and the medium passes through the valve smoothly; when the medium has a tendency to flow back, the valve disc quickly falls back under the combined action of its own gravity and the reverse pressure of the medium, fits tightly to the valve seat, blocks the medium backflow channel, and thus achieves the function of preventing the medium from flowing back. This automatic opening and closing feature does not require an external power source and can be completed by relying on the energy of the medium itself, greatly reducing the operating cost and maintenance difficulty.

Product advantages

1. Excellent sealing performance: cast steel lifting check valve can achieve good sealing effect through precision machined valve disc and valve seat, as well as unique lifting structure design.

2. Long service life: due to the use of high-strength cast steel material and high-quality components, cast steel lifting check valve has a long service life.

3. Good pressure resistance: Cast steel material itself has high pressure resistance, so that cast steel lifting check valve can withstand greater working pressure.

4. Convenient installation and maintenance: The flange connection method makes the installation and disassembly of cast steel lifting check valve very convenient, which is convenient for the installation, commissioning and maintenance of the pipeline system.
