CPC G05D 16/028 (2019.01) [G05B 15/02 (2013.01); G05D 16/2013 (2013.01)] | 11 Claims |
1. An operating method for a valve system having a valve with a moveable armature and a pneumatic actuation apparatus, the method comprising:
a) providing, by a controller, the valve in an active operating state and specifying a valve position to be approached;
b) determining, by the controller, a target differential pressure corresponding to the valve position to be approached which is to be set in the pneumatic actuation apparatus;
c) changing, by the controller, a differential pressure present in the pneumatic actuation apparatus and detecting the differential pressure present; and
d) stabilizing, by the controller, the differential pressure present when a deviation between the differential pressure present and the target differential pressure falls below a settable threshold value in terms of amount;
wherein the valve position to be approached lies between two end positions of the moveable armature; and
wherein the operating method comprises self-calibration of the valve system in which the end positions are approached to determine a pressure-time characteristic.
