<p>A modular system to form valve batteries comprises a plurality of valve units (11) to be variously packed in side by side relationship to form the battery. Each valve unit has a face (40) on which outlets for the users appear and through ducts (23, 24, 25) appear on lateral sides thereof, which are intended for being juxtaposed and connected with corresponding ducts (23, 24, 25) of units in side by side relationship. The valve units generally are of parallelepiped shape, the sizes of the mating sides (21, 22) being substantially constant for all units and the thickness of each unit varying on varying of the maximum flow rate of the specific valve unit, to enable a direct coupling between valve units having different maximum flow rates. <IMAGE></p> |
