A valve arrangement for regulated provision of a fluid relies upon a pilot control unit. The pilot control unit includes at least one electrically controlled pilot control valve and one regulating unit coupled to the pilot control unit. The regulating unit is designed for the adaptive, parameter-based regulation of the at least one pilot control valve. The regulation is based on a combined parameter which describes an opening point of the at least one pilot control valve. A determination of the combined parameter is made based on a static component and a dynamic component.

Pilot control unit, valve arrangement, and method for the regulated provision of a fluid

A device for providing an output fluid at a regulated output pressure includes a pressure control unit controlled via a pilot control pressure and a pilot control unit that provides the pilot control pressure. The pressure control unit includes an inlet chamber for an input fluid having an input pressure, an outlet chamber for the output fluid having the regulated output pressure and a first valve unit that acts between the inlet chamber and the outlet chamber. A first diaphragm of the pressure control unit is acted upon by the pilot control pressure. A second diaphragm, which is mechanically coupled to the first diaphragm is acted upon by the output fluid having the output pressure acts. At least the second diaphragm mechanically acts on the first valve unit.
