<p>In a concealed sanitary valve unit the valve body received in a concealed outer housing is made from plastic material. In order not to exert excessive mechanical loads, particularly torsional and tensional loads onto the valve body improved clamping means are provided which will exert onto the valve body only small compressive loads. Connection of the valve body to the feed and work lines extending through the wall is achieved without making use of threadings, since connecting nuts are fixed to the feed viz. work lines having plane end faces adapted to sealingly engage plane connecting faces of the valve body.</p> |
