GEMÜ has released two new videos, where a service trainer from its training team explains the setting of closing and opening limits in diaphragm valves. With this functionality, diaphragms in the pharmaceutical industry and for applications in the beverage and foodstuff industry reach a longer service life.
High temperatures, frequent switching and high pulse frequencies put a great deal of stress on wearing parts, such as diaphragms. In extreme applications, diaphragms are exposed to high thermal and mechanical stress. The accelerated aging which results from this can lead to premature damage. For instance, a travel stop can prevent a shut off diaphragm that has been softened by the high temperature influence from being compressed too much, which can occur in manually operated valves in particular. By contrast, in pneumatic and motorized valves, the travel stop prevents the diaphragm from being exposed to the maximum closing force during every closing process. Opening limiters are also explained in detail in the films. These limit the volumetric flow required and prevent full opening, thereby minimizing the mechanical stress on the diaphragm.
In the video series, the GEMÜ service trainers clarify situations that frequently arise in practice and can lead to problems in operation.
