Valve assembly comprising an internal flow channel with an open longitudinal section

A valve arrangement, comprising a plurality of valve units (2), which on opposite sides thereof respectively have a mounting face (5 and 6) and which with the formation of a subassembly are arranged in an array direction (3) one after the other and thereby are mounted side by side with mounting faces (5 and 6) thereof facing each other, each valve unit (2) possessing two internal flow ducts (32a and 32b) running athwart the array direction (3) and designed in the form of power ducts, such ducts extending from a valve means (14) of the respective valve unit (2) to one and the same outer face, aligned athwart the array direction (3) of the valve unit (2), where connection means (33) for the connection of a fluid duct leading to other equipment are provided, characterized in that the two internal flow ducts (32a and 32b) are delimited at their first longitudinal side (34a and 34b), facing the first mounting face (5), by a respective lateral duct wall (36a and 36b) of the respective valve unit (2) and at their second longitudinal side (35a and 35b), facing the other second mounting side (6), are open along a length section (37a and (37b) extending at least along a part of their length, and the open length sections (37a and 37b) have a sharply bent or arcuate shape in the length direction thereof and are covered by the lateral wall (36a and 36b) of the neighboring valve unit (2) mounted on the second mounting side (6).
