<p>An improved modular manifold (40) for heating and sanitary systems comprising tubular manifold modules (21; 50, 51, 60, 61; 70, 71, 80) having integrally formed end coupling means (22, 23; 53, 54) and either only a branch union (4) or a branch union (4) and an adjusting union (3) for receiving a branched circuit pipe and a shutter mechanism (62), respectively. Metal pre-shaped blanks (1) are provided for producing said manifold modules (21; 50, 51, 60, 61; 70, 71, 80) by hot-pressing and chip-forming machining steps. Plastics manifold modules (21; 50, 51, 60, 61; 70, 71, 80) may also be injection molded.</p> |
