Product Structure Features
API cast steel gate valves are used to cut or connect the pipe media in Class 150~2500 and working temperatures ≤600℃, in oil industry, chemical industry, fossil-fired power plants.
The main structure features include:
1.The products designs are in accordance with the API600 or API6D, with rational structure, reliable seal, excellent performance, and pretty appearance.
2.Co hard alloy welded sealing surface、with pressures≥Class600 which is wearing resistant, erosion proof, abrasion proof and long-lived.
3.The surface and the adjusting media of the valve shaft are nitrogenizated so that it is erosion and abrasion resistant.
4.The central cavity with pressures≥Class900 adopts self-tightening sealing structure,which means that the sealing will rise with the intramural pressure, and the sealing is highly reliable.
5.There is backward sealing structure in the valve, so the sealing is reliable.
6.The material of the filling and the size of the flanged ends & butt-welding ends can be chosen and matched according to the applications and the applications and the requirements of the users. That can satisfies all kinds of working requirements.
