This paper reports a new proportional flow control valve for pneumatic actuators. We have researched valves that use particle excitation with a piezoelectric transducer. The valves have high flow rate/weight and high controllability. In this report, we introduce a new proportional flow control valve using particle excitation by piezoelectric transducer. The valve is composed bolt-clamped Langevin-type transducer (BLT) and the flow rate is proportion to the applied voltage at the transducer. We have designed a prototype of the valve using finite element method (FEM) and measured flow rate characteristics by experiments. In the results of the experiments, we have confirmed that the control flow rate is proportionate to the applied voltage at the transducer and
maximum flow rate is about 70 L/min under 0.5 MPa.
