Assemblies

Coordinated, ready for installation directly on the production line

Customized assemblies

We manufacture assemblies such as valves (including mini-valves), tees, elbows and many more according to customer specifications.

Applications

  • Fuel distributor
  • Check valves with defined opening pressure (e.g. 0.2 bar)

  • Filter strainers (hydraulics)

Procedure

Mounting

  • Cutting ring pre-assembly by pre-assembly device
  • Joining by press-fitting (for subsequent brazing)
  • Joining by fixing with spot weld (for subsequent brazing)

Soldering
