The wafer lifting check valve has taken advantages of the lift check valve and the wafer check valve. The wafer lifting check valve is available in standard forged or cast carbon steel, stainless steel, duplex stainless steel and monel and others. It is certain that the difference on the materials would influence the practical performance of the specific wafer lifting check valve.
Similar to other types of the check valve, the
wafer lifting check valves are opened by the fluid flow and closed as far as fluid flow stops or reverses direction. The wafer lifting check valves are popular for some outstanding features. Several features are listed in the following:
1. It is in small face to face dimension in most cases.
2. It is designed with small volume and weight.
3. Disc can be quickly closed which ensuring a very small water hammer pressure.
4. Perfect flow passage gives a very small flow resistance.
5. The valve itself can be easily installed onto pipelines both in vertical and parallel style.
6. Flexible actions and perfect sealing enable the good performance.
7. The disc of the wafer lifting check valve is with a short travelling journey which ensuring a very small impact caused by valve close
8. As Integral Designed, the wafer lifting check valve is able to be provided with a compact structure and beautiful appearance.
9. Wafer lifting check valve is provide with a device preventing flow direction reverse or stop which can be controlled automatically.
10. The wafer lifting check valve is able to serve a long time.
