Valves as Welded Construction

A flexible Solution for large Nominal Diameters


Welded constructions are a flexible solution for valves with large nominal diameters. In addition a combination of various materials and production techniques is possible. In so doing, steel elements can be reasonably completed with parts made of stainless steel and solid material. This process is very cost-effective for limited-lot or single-item productions and simultaneously offers a lot of flexibility with regard to your requirements.


Customised for your Application

  • shorter delivery times compared with cast designs
  • use of special materials
  • lighter weight, compact design
  • single-item productions are possible
  • short-notice change of design, e.g. flange standard or adapted building length
