Manually operated fluidic multicoupling type 90405, 90408 and 90410 The manually operated fluidic multicouplings are used e.g. for pneumatic measuring, control and monitoring loops and are supplied ready to be installed. Technical Data: number of connections: 4 to 20 pressure range: up to 10 bar diameter: n.b. 2-4 mm Manually operated multicouplings WALTHER-PRAEZISION offers different designs of manually operated multicouplings for the simultaneous connection of several fluidic, pneumatic and electrical lines. Due to the fixed arrangement of the coupling elements mistakes are excluded and the duration of the coupling procedure is enormously shortened. Multicouplings are used therefore there, where automatized operating procedures during manufacturing, testing, actuating and controlling are requested.
