In addition to the Kits or Seat Assemblies we are able to supply the series of springs made of materials that best suit the valve applications, taking into account the calculation parameters (wire diameter, number of turns, distance between the turns, height, compression loads, etc.).

The materials proposed are mainly: Inox F301, F302, F304, Inconel 625, 718, 725, 825, Elgiloy, and others.
