Flange stainless steel gate valve are used to cut or connect the pipe media under nominal pressure between PN1.6~42.0MPa(Class 150~2500),working temperatures ≤600ºC. in oil industry,chemical industry, fossil-fired power plante.

The main structure features include
1.The design and manufacture are in strict accordance with GB /T12234, API600 and API602. The product has reasonable structure, reliable sealing, excellent performance and beautiful appearance.
2.The sealing surface is overlaid with Co based cemented carbide, which has good wear resistance, corrosion resistance, abrasion resistance and long service life.
3.After quenching and tempering and surface nitriding treatment, the valve stem has good corrosion resistance and scratch resistance.
3.When the nominal pressure is more than or equal to 15.0mpa (class900), the self tight sealing structure is adopted in the middle chamber, and the sealing performance is enhanced with the increase of pressure to ensure the sealing performance.
5.The valve is equipped with reverse sealing structure, which is reliable
6.Parts material, flange and butt welding end size can be reasonably selected according to actual working conditions or user requirements 7.The valve model is compiled according to JB / t308 "valve model preparation method"
