Flange ends cast steel gate valve are used to cut or connect the pipe media under nominal pressure between class150-2500, workin

The main structure features include:

1.      Both design and manufacture are carry out strictly fellow API600 and API602. The products feature a reasonable structure, reliable seal, good performance and nice modeling.

2.      Co hard alloy welded sealing surface, which is wearing resistance, 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 resistance.

4.      Class≥900LB, the media 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 backward sealing structure in the valve, so the sealing is reliable.

6.      The material of the filling and the flange size can be chosen and the matched according to the applications and the requirement of the wiers. That can satisfy all kinds of working requirements.
