Pressure control configuration
The valve has four identical pressure controller units. Controller Selector defines which unit is used for
the pressure control.
Most applications do not need more than one controller units. But if the result of the pressure control does
not meet the expectations, the different controller units can be an option for optimization: With the four
controller units it’s possible to use an own controller unit for a specific pressure working point. This
controller unit can be parametrized optimally for this specific working point.
