Forged steel valves are: gate valves, globe valves, lift check valves, swing check valves. Small diameter valve body if the casting, the possible existence of internal porosity, trachoma, loose and many other casting defects. And forged steel gate valve body blank after forging, the material organization fiber, less defects, high strength. It is characterized by strong pressure resistance, high reliability and long service life.
Forged steel valves are suitable for pressure Class 150~2500,, PN10~PN420, working temperature -46-600 ° C petroleum, chemical, pharmaceutical, fertilizer, electric power industry and other working conditions of the pipeline. Valve structure is compact, installation occupies little space.
Its main structural features are:
1. The valve can be used: bolted bonnet structure, pressure-sealed bonnet, welded bonnet form.
2. sealing surface surfacing cobalt-based cemented carbide, wear-resistant, corrosion-resistant, anti-scratch performance, long service life.
3. the valve connection form: flange, socket welding, butt welding, threaded, etc., a variety of forms, a wide range of applications.
4. The surface of the valve can be blackened: blackening is the common name for the surface oxidation of steel parts. The main component of the oxide film is Fe304, black, dense and firm, is the most ideal composition of the oxide film of steel parts, blackening generated by the dense oxide film on the surface of the workpiece to play a role in preventing rust, increase the surface of the workpiece beautiful and shiny. Can also be painted, according to the need for processing.
