The torque block^® enables highly dynamic analogue valve control in piezo actuator drives. One feature of the gas-dosing valve is that the valve stroke and thus the aperture cross section of the valve can be regulated from 0 - 100 %.

The highly dynamic nature of the drive also enables short opening pulses. The analogue or digital function of the valve is determined purely by the electronics.

Due to the high mechanical resonance frequency, the valve's characteristic curve follows the controller well above 1 kHz.

Application

The gas-dosing valve is used to dose gaseous non-aggressive media. The dosage can ensue quasi static (analogue) or through short gas pulses (digital).
