As the title suggests, does anyone know what purpose this part of the piezoelectric module in Siemens positioners serves? As shown in the figure, thank you!
In a Siemens positioner, the piezoelectric valve is a crucial component – it determines whether pilot control leads to intake or exhaust. Piezoelectric valves offer high control sensitivity and low power consumption.
