Diaphragm replacement GEMÜ Code 5M at the GEMÜ 650 BioStar diaphragm valve

In this video we show you the diaphragm replacement of the two-piece GEMÜ Code 5M PTFE diaphragm at the GEMÜ 650 BioStar diaphragm valve. Compared with the previous GEMÜ Code 5E diaphragm that is tightened until a slight bulge can be seen, the GEMÜ Code 5M diaphragm is fitted level and parallel to the valve body. A compression is not visible externally. Please observe the safety information and regulations. You can find further information in our assembly instructions.
