4.2 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.

Actuation is handled by a stepper motor with an encoder monitoring the position. This principle
ensures very fast and accurate process pressure control even in demanding contaminating processes.
