<p>The valve (5) comprises a hollow body (10) into which the inlet (8) flows. The body supports a closing bar (6) and an insulating drop for the threaded housing of the resistance .The centers of the orthogonal sections of the inlet (8) and the outlet (9) lie on the same vertical plane perpendicular to the plane of the wall supporting the radiator (3). The resistance is inserted into a vertical tube of a radiator and is fed by current of an electric network or the like by use of a plug (4).</p> |
