Piezoelectric Ball Valve. A schematic illustration of the reversible piezoelectric ball valve is shown in the figure. The piezo valve consists of input and output tubes, a spherical saddle, a turn ball and a bidirectional piezomotor. The regulator function of the valve is performed by precise rotation of the turn ball attached to the piezomotor. The reversible design of the valve enables rotation of the turn ball in either direction, providing continuous control of flow rate. An optical encoder...
