Product structural features
Flanged ends cast steel gate valve are used to cut or connect of pipe medium under norminal pressure between PN1.6~16.0MPa(Class150~2500)working temperatures≤ 600° C. In petroleum, chemical industry, pharmacy, chemical fertilizer, and power industry.
The main structure features include:
1, Both design and manufacture are carried out strictly following GB/T12234, API600, API602. The products feature a reasonable structure, reliable seal, good performance and nice modeling.
2, Co hard alloy welded sealing surface, which is wearing resistant, erosion proof, abrasion proof and long-lived.
3, The surface and the adjusting media of the valve shaft are nitrogenized 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 rise so 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 chosen and matched according to the applications and the requirements of the use's. That can satisfies all kinds of working requirements.
