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.

Q: After setting the manual handle to the specified position, it may unintentionally move, causing the opening degree to change. What is a way to prevent such a manual handle from moving? A: The GEMU manual diaphragm valves model 653 and 654 have a specification with a handle lock that can fix the handle in the specified position, allowing for adjustment of the opening degree only when necessary. *There is also an electric specification that uses a solenoid valve for locking, rather than a mechanical one. Please refer to the instruction manual for more details.

Aren't you worried about how much to tighten the handle before it closes, and end up tightening it too much? Over-tightening the handle can lead to damage to the diaphragm that stops the fluid. This product comes standard with a system called "Seal Adjuster," which allows you to adjust the fully closed position of the valve! By using this system, you can achieve: 1. Prevention of diaphragm failure due to over-rotation of the handle 2. Adjustment of flow rate. There is a clear difference in strength between women and muscular men, which affects how much force they can apply to turn the handle. However, by setting the fully closed position, anyone can close the valve at the same position regardless of their strength! Additionally, it can fulfill the desire to adjust the flow rate consistently just by turning the handle. Setting the Seal Adjuster is also very easy!
