Function of valve

The valve plate acts as a throttling element and varies the conductance of the valve opening. The
controller calculates the required plate position to achieve the set point pressure. Actuation is
performed by one synchronous stepper motor. Encoder monitors the position. This principle ensures
fast and accurate process pressure control.
