API 6D Standard Cast Steel Bolted Bonnet Flanged Globe Valve Class 150 - 900
Products Design Features
ANSI cast steel globe valves are used to cut or connect the pipe media in Class 150~2500 and working temperatures≤600°C, in oil & chemial industry, thermal power station.The products designs are in accordance with the ANSI B16.34 and BS 1873, with rationalstructure, reliable seal, excellent performance, and pretty appearance.Cabalt base alloy welded sealing surface, anti-wearing, erosion-proof abrasion-proof and longer use life.
The surface and the adjusting media of the valve shaft are nitrogenized so that it is erosion and abrasion resistant.The central cavity with pressures rating Class≥1500 adopts self-tightening sealing structure, which means that the sealing will rise with the internal pressure, and the sealing is highly reliable. There is back seat structure in the valve, so the sealing is reliable.
The material of the parts and the flange sizes can be chose and matched according to the applications and the requirements of the users. That can satisfies all kinds of working requirements.
