Lift Check Valve refers to the valve that automatically opens and closes the valve flap depending on the flow of the medium itself to prevent the medium from flowing back. It is also called check valve, one-way valve, reverse flow valve, and back pressure valve. Lift Check Valve is a check valve whose disc slides along the vertical centerline of the valve body. It can be divided into two types: vertical and horizontal. The connection form can be divided into three types: threaded connection, flange connection and welding.

1) The Lift Check Valve is exquisitely selected and meets relevant domestic and foreign standards, and the overall quality of the materials is high.
2) The Lift Check Valve sealing pair is advanced and reasonable. The valve disc and valve seat sealing surface are made of iron-based alloy or cobalt-based cemented carbide. It has good wear resistance, high temperature resistance, corrosion resistance, scratch resistance and good service life. long.
3) Lift Check Valve products are designed and manufactured according to the national standard GB/T12235.
4) Lift Check Valve has a small opening pressure, and the valve flap can be fully opened under a small pressure difference.
5) The Lift Check Valve adopts a self-tightening sealing structure, and the sealing performance is enhanced as the pressure rises to ensure the sealing performance.
5) Lift Check Valve has a complete range of body materials, and gaskets can be selected according to actual working conditions, which can be applied to various pressure, temperature and medium working conditions.
The Lift Check Valve produced by Milestone Valve Company can be applied to water, steam, oil, nitric acid, acetic acid, and strong oxidizing media; it is mainly used in pipelines such as petroleum, chemical, pharmaceutical, and electric power.
