Gate Valve
application:
Flanged ends cast steel gate valve are used to cut or connectthe pipe media under nominal pressure between PN1.6-42.0MPa (Class150-2500),working temperatures ≤600℃.in oil industry, chemical industry, fossil-fired power plants.
The main structure features include:
1,Both design and manufacture are carried out strictly following GB/T12234,API600 and API602.The products feature a reasonable structure,reliable seal,good performance and nice modeling.
2,The sealing surface is welded with Co based cemented carbide, which has good wear resistance, corrosion resistance, abrasion resistance and long service life.
3,The surface and the adjusting media of the valve shaft arenitrogenized so that it is erosion and abrasion resistant.
4,PN≥15.0Mpa(class900),the middle cavity uses a self-tightening sealing structure to have the sealing performance reinforced along with the pressure riseso as to ensure the sealing performance.
5,There is no backward sealing structure in the valve,so the sealing id reliable.
6,The material of the filling and the flange size can be chosenand matched according to the applications and the requirements of the use's. That can satisfies all kinds of working requirements.
