Abstract
A method of controlling a valve plunger of a valve makes provision that, prior to the operation, the valve individually runs through a set-up procedure on the basis of a detected closed position, in which set-up procedure the valve plunger exerts an additional force in the direction of the valve seat beyond a detected closed position. The corresponding valve is equipped with an integrated valve controller which performs a corresponding set-up procedure automatically prior to the operation.

Method of controlling a valve, which has a valve plunger, wherein, prior to operation, the valve individually runs through a set-up procedure on the basis of a detected closed position, in which set-up procedure a first closed position of the valve plunger is detected, wherein during subsequent, continuous operation the valve plunger is moved beyond the detected first closed position to a second closed position in which it exerts a force on the valve seat which comprises an additional force added to that applied in the first closed position,
- wherein the first closed position is detected by sensors and on the basis of at least one detected value, desired parameters for the second closed position are determined, and
- wherein flow through the valve is detected by sensors during the set-up procedure, and from a point where a predetermined lower limit value of the flow is achieved, the first closed position is stored.
Valve comprising a valve drive and a valve plunger, which is actuated by the valve drive, and an electronic valve controller integrated in the valve, wherein in the valve controller, a set-up procedure is stored which comprises, prior to the operation, individually running the valve through a set-up procedure on the basis of a detected closed position, in which set-up procedure a first closed position of the valve plunger is detected, wherein during subsequent, continuous operation the valve plunger is moved beyond the detected first closed position to a second closed position in which it exerts a force in the direction of the valve seat which comprises an additional force added to that applied in the first closed position,
- wherein the first closed position is detected by sensors and on a basis of at least one detected value desired parameters for the second closed position are determined, and
- wherein flow through the valve is detected by sensors during the set-up procedure and from the point where a predetermined lower limit value of flow is achieved the first closed position is stored.
