In this repot, we decided the optimum design of the orifice arrangement and orifice diameter for this valve to achieve continuous flow control. And we designed new flow control valve prototype that the orifices were arranged from the center at 0.2-mm intervals. We have measured flow rate characteristics, hysteresis characteristics and observed vibrational acceleration. We conclude that the orifice pattern arranged from the center at 0.2-mm intervals with φ0.4-mm orifices is most suitable for continuous flow control.Read More
