Disclosed is a valve apparatus having a first pressure compensation valve, a first, gas-tight, cap-like membrane device, and a gas-permeable, moisture-permeable, and yet water-impermeable second membrane device. The first pressure compensation valve, in particular a back-pressure valve, having a first valve housing, which limits a pressure compensation opening and comprising a housing side and a covering side, comprising or consisting of a first, gas-tight, cap-like membrane device covering a first pressure compensation opening and releasing the first pressure compensation opening from a predetermined negative pressure prevailing on the housing side in order to enable a pressure compensation between a housing device and an environment, and a gas-permeable, moisture-permeable, and yet water-impermeable second membrane device arranged on the covering side and in series to the first membrane device, covering a second pressure compensation opening and preventing water entry into the valve housing and thus into a housing device.

Disclosed is an apparatus, in particular a valve apparatus, for sealingly connecting to an opening of a carrier component. The apparatus includes a base body made of a hard component for the connection to an edge of a carrier component delimiting an opening, and a sealing device made of a soft component. The base body comprises at least one connection passageway configured as an undercut for the form-fit connection to a correspondingly configured element of the soft component, and a lid element for covering the connecting region.
