The Manufacturing Process of Industrial Valves
To produce the valve, including these procedures: Design Drawing, wax molding, dissolving steel, casting, cleaning up, casting product inspection, machine processing, testing tolerance, grinding surface, surface inspection, appearance electroplating, assembling, testing pressure, testing temperature, testing material, finished product inspection, packed in wooden cases, the valve can leave the factory after these complex process.
In the open die forging sector, dimensional controls are usually carried out in manual ... system for the 3D survey and dimensional check of hot or cold forgings.
This includes the manufacturing of components, like bodies, caps and bonnets. Valves are manufactured through the process of forging or casting. The common perception is that forging is a superior method, but modern-day manufacturers are getting equally brilliant results with casting.
We are able to execute mechanical precision-processings and a great variety of materials for which specific competences are a must: Duplex stainless steel, various titanium, nickel, chromium and other materials.
