た。<Prior art> For example, when adjusting the flow rate in a ball valve, it is done by adjusting the rotation amount of the operating lever, but in conventional ball valves, a stopper is used to restrict the rotation of the operating lever at the fully closed or fully open position. Since only one valve is provided, it is difficult to adjust the opening with reproducibility, and once the valve is closed, the valve must be set to the same opening again to obtain the required flow rate. A difficult problem arose.
