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.
