【Q&A】What is the maximum temperature that sterilization and cleaning processes can withstand?
We will answer your valve concerns!
Q: Is it possible to sterilize and clean the piping of a manual diaphragm valve at 120°C (SIP/CIP)? Additionally, what is the expected temperature rise at the handle during this process? A: The maximum temperature for steam sterilization is 150°C, and the temperature rise at the handle is approximately 45°C, so it can be safely operated even after the sterilization process. *Please inquire as the heat resistance duration may vary depending on the diaphragm. *For autoclave processing, some products may not be compatible, so please inquire.
