Lift Check Valve

Lift check valve is a valve that automatically opens and closes the valve disc by the flow of the medium itself to prevent the backflow of the medium. It is also called a non-return valve, a one-way valve, a reverse flow valve, and a back pressure valve. A check valve is an automatic valve. Its main function is to prevent the backflow of the medium, the reverse rotation of the pump and the drive motor, and the release of the container medium. The check valve can also be used on the pipeline to provide supply to the auxiliary system where the pressure may rise to exceed the system pressure. Check valves can be mainly divided into swing check valves (rotating according to the center of gravity) and lift check valves (moving along the axis).

Product features:

The materials are carefully selected and meet the relevant domestic and foreign standards. The overall quality of the materials is high.

The sealing pair is reasonably matched. The valve disc and valve seat sealing surface are made of iron-based alloy or Stellite cobalt-based hard alloy surfacing, which has good wear resistance, high temperature resistance, corrosion resistance, abrasion resistance and long service life.

Various piping flange standards and flange sealing types can be used to meet various engineering needs and user requirements.

The valve body material variety is complete, and the gasket can be reasonably selected according to the actual working conditions or user requirements. It can be applied to various pressure, temperature and medium working conditions

The flange lift check valve is suitable for pipelines with a nominal pressure of PN 1.6 ~ 6.4 MPa and a working temperature of -29 ~ 550, and is suitable for various working conditions such as petroleum, chemical industry, and thermal power stations. Applicable media: water, oil, steam, etc.
