3.2 Function
The valve plate (5) acts as a throttling element and varies the conductance of the valve opening.
The integrated controller (1) calculates the required plate position to achieve the setpoint pressure.
See also principle drawing on chapter: «Connection Overview».
Actuation is performed by a stepper motor. An encoder monitors the position. This principle ensures
very fast and accurate process pressure control even in demanding contaminating processes.
