Flanged ends cast steel gate valve are used to cut or connect the pipe media under nominal pressure between PN 1.6~25.0MPaworking temperatures between-29~600°C, in oil industry, chemical industry, fossil-fired power plants.

The main structure features include:

1.Sensible products structure, reliable sealing. Excellent performance and good looking.

2.Cobalt base 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.There is no backward sealing structure in the valve, so the sealing id reliable.

5.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.
