A membrane valve, with a valve housing, in which a housing interior is formed, in which housing interior a flexible control membrane is arranged. A drive plunger lies opposite a valve seat and the drive plunger has a shank body with a peripheral outer lateral surface. The outer lateral surface of the shank body of the drive plunger at least in the region of a guide section has a polygonally contoured prismatic shaping with a succession of outer side edges and outer side surfaces, wherein the edges and surfaces extend in the plunger longitudinal direction and the succession alternates in the circumferential direction of the drive plunger.

Membrane valve

Fluid assembly for use in a fluid system, having a control module including a processing unit for processing control commands into individual electrical control signals with individually adjustable control signal levels and a control signal level electrically connected to the processing unit, with a power unit, which has a power module for converting the control signals into individual electrical control currents as a function of the control signal levels and an output interface electrically connected to the power module, wherein the processing unit is designed to provide a first group of control signals in a first time interval which can be individually predetermined for each control signal and to provide a second group of control signals in a second time interval which can be individually predetermined for each control signal and follows the respective first time interval, wherein the first control signal and the second control signal are selected in such a way that the control currents in the first time interval are greater than the control currents in the second time interval.
