The new CN Series of multiple clean-break quick-coupling systems (photo) is designed for industrial filling systems where a mix-up of media could have dire consequences. The coupler features a cam-lock action, which facilitates the connection, even at residual pressure. The operator only has to turn the coupling by 120 deg to lock it and to quickly connect the lines. During this rotary motion, the valves are opened. Very little effort is needed for connection since the axial forces required to operate the internal valves are reduced by the cam action. The CN Series is suitable for the transfer of aggressive or hazardous fluids. These couplings are available in nominal sizes of 25, 40 50, 80 and 100 mm. Depending on the size, the nominal pressure ranges from 10 to 25 bar. — Walther-Präzision, Carl Kurt Walther GmbH & Co. KG, Haan, Germany
