Ball valve parts
We are specialists in the production of ball valve parts and are known for our ball valve seat assemblies: the absolute summit of a custom-made product. We compile this seat assy from multiple parts of different materials.
Our ball valve parts are used in the marine, offshore and chemical industries, as well as in transport and transshipment (specially for liquid transport and LNG transport) and other sectors.

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.
