Pneumatic valve arrangement and method of operating a pneumatic valve arrangement

A pneumatic arrangement comprising:

• a pneumatic valve arrangement having a pneumatic valve unit including an input port for receiving compressed air and an output port for controllably providing the compressed air;
• said pneumatic valve unit further including an actuator unit configured to actuate a pneumatic connection between said input port and said output port;
• said pneumatic valve unit further including a valve-control unit configured to control said actuator unit of said pneumatic valve unit;
• said valve-control unit being configured to:
• ascertain a respective actuation function associated with each of a plurality of available air flow characteristics;
• ascertain, from the plurality of available air flow characteristics, a target air flow characteristic for delivering the compressed air by said pneumatic valve unit;
• and,
• control said actuator unit using the actuation function associated with the target air flow characteristic for delivering the compressed air in accordance with the target air flow characteristic;
• a compressed air supply unit connected to said input port of said pneumatic valve unit and configured to supply compressed air to said input port of said pneumatic valve unit;
• and,
• a pneumatic unit connected to said output port of said pneumatic valve unit and configured to receive the compressed air from said output port of said pneumatic valve unit for operation of said pneumatic unit.

A method for controlling a pneumatic valve arrangement, the method comprising:

• ascertaining a respective actuation function associated with each of a plurality of available air flow characteristics;
• ascertaining, from the plurality of available air flow characteristics, a target air flow characteristic for delivering compressed air by a pneumatic valve unit;
• and,
• controlling an actuator unit using the actuation function associated with the target air flow characteristic for delivering the compressed air in accordance with the target air flow characteristic.
