<p>The arrangement (1) has a valve block group (6) held by operation duct systems (36, 36a, 36b, 36c). The operation duct systems are assembled of individual operation channels (33, 33a, 33b, 33c) of a valve block (5) communicating with each other in a region of mounting surfaces (8a, 8b). A shutoff valve (43) is switched by the duct systems in the channels of the valve block. The shutoff valve optionally releases or closes a fluid connection to an actuating chamber (32) of a pinch valve (18) without interrupting fluidic cross-linking of the valve block caused by the duct system.</p> |
