Abrégé

A linear valve drive for connection to a valve body which has a valve seat is described, wherein said linear valve drive comprises a drive housing, a valve closure element and a piezoelectric actuator which is arranged within said drive housing. Said valve closure element is displaceable in the axial direction between an open position and a closed position by means of said piezoelectric actuator and an interposed actuating device. Said piezoelectric actuator is supported on said actuating device via its side directed towards the valve closure element. Said linear valve drive comprises an adjusting device which is configured such that an idle stroke of said linear valve drive is adjustable. A valve is also described.

Abrégé

A valve assembly with at least two valve modules is described, wherein the valve modules are arranged one beside the other in a line-up direction. The valve assembly also comprises an indicating device for displaying a state of the valve modules and/or of the valve assembly and/or of a component connected to the valve assembly. In the line-up direction the indicating device continuously extends over all valve modules.

Abrégé

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.
