Until now, it was not possible to predict gradual changes in the valve parts during the closing process. The result was often costly measures to prolong the service life. Thanks to intelligent measuring technology, it is now possible to detect any possible seal wear at an early stage.
In form- and core-shooting machines, which work with the air-flow method, the quartz sand mixed with binder is shot at high pressure into a core box. The closing fitting of the core box in this application - the butterfly valve - is thus exposed to extreme pressure conditions, which it has to withstand - a great challenge for the plant operator.

Regardless of whether production facilities already exist or are to be newly built. the demands on their performance requirements are increasing. This requires specially adapted valves to control and regulate solid flows.
