Valve parts

Seat assembly: our specialty

Thanks to our years of experience, also of shrinkage and expansion of the different materials, fitting all loose parts into a seat assembly has become one of our specialties. In our machine shop, we have specialists for turning metals, carbon graphite and plastics. Machining plastics or carbon graphite are very different specialisms than machining metals. Every plastic or graphite behaves differently under external factors such as temperature and humidity. We guarantee a high level of accuracy in all turning and milling. Depending on the material, we can work to tolerances up to 0.05 mm.
