Ball valve parts

Ball valve seat assy

Our seat assembly always consists of multiple parts in different materials. Thanks to our years of experience, also of shrinkage and expansion of the different materials, fitting different parts into a seat assembly has become one of our specialties. Often metals are combined with graphite (hard or soft) and plastics. A seat assy is assembled in the following way:

  • Ball valve seat (front seal / retainer)
  • Ball valve retainer (zittinghouder)
  • Ball valve seal (rear seal)
  • Possible addition: o-ring or backup ring

Machining plastics or carbon graphite are very different specialisms than machining metals. Every plastic or graphite behaves differently under external factors. We machine all parts of the seat assy in-house. In our machine shop, we have specialists for turning metals, carbon graphite and plastics.
