The disclosure relates to a process valve for a media flow path, particularly for use in the beverage industry or pharmaceutical, chemical and food industry, including at least one valve disk, at least one primary seal lying on the valve disk, at least one secondary seal, and at least one hollow space bounded by at least one primary seal and at least one secondary seal having at least one conically tapered groove for holding the secondary seal. The secondary seal is incorporated in such a manner that it seals on only one side and is permeable to media that flow out of the hollow space.
