Application.

  For valves which size is smaller than 2"(DN50), forged steel valves are recommended. Compared with castings,forged valve offer the advantages of more uniform structure, greater density, higher strength integrity, enhanced dimensional characteristics and closer dimensional tolerances.Owing to so many advantageds,the forged valve can be widely used in the fields of petroleum,natural gas,chemical,power and other industries.
