The valve insert is inserted in a replaceable and sealing manner in the valve receptacle. The valve insert has a stop portion, a fastening portion distinct therefrom and a sealing portion distinct from both. The associated valve receptacle has stop, fastening, and sealing portions matching the equivalent portions of the valve insert. When the valve insert is installed correctly both the stop portions and the sealing portions bear on one another in a planar manner. |
