The paper presents the design and the construction of the power part of a three-way pneumatic valve that uses a pilot stage developed by Belforte et al., based on a compact turbulent amplifier that uses the laminar-turbulent transition of fluidic jets. The valve can be used to drive a power stage of pneumatic circuits. It has a low energy consumption to switch. The pilot stage uses an acoustic signal generated by a piezoelectric device to brake the laminar flow. The power part of the valve has been designed to obtain an high conductance and a good dynamic performance. The design of the power valve, by a mathematical model using concentrated parameters, is presented. The prototype was constructed and tested. The results of the experimental test are also reported and discussed.

The valve can be used to drive a power stage of pneumatic circuits. It has a low energy consumption to switch. The pilot stage uses an acoustic signal generated by a piezoelectric device to brake the laminar flow. The power part of the valve has been designed to obtain an high conductance and a good dynamic performance. The design of the power valve, by a mathematical model using concentrated parameters, is presented. The prototype was constructed and tested.
