New clean break coupling for high-pressure applications

This new “DD” quick coupling series is designed specifically for use under high-temperature chemical conditions, for hydraulic applications with high thermal loads, for synthesis processes, as well as for special applications within the petro-chemical sector. Depending on the nominal widths, it is suitable for operating pressures of up to 250 bar. The components are made from high-quality materials that are both thermally and chemically resistant, and may thus be used for critical gases and liquids up to a temperature of 250 °C. The coupling is manufactured using high-quality stainless steel and the smooth surfaces ensure easy cleaning of the quick coupling along with long service life. In addition, the service-friendly design with removable valves and replaceable O-rings considerably reduces the operating costs of the system in the long-term. The couplings are available in the nominal widths DN 6, 9, 12 and 16 mm and are also, typically for WALTHER, already available with multiple connection versions.

Another focus of the exhibits presented by WALTHER is the tried and tested clean break quick couplings of the CN series, fitted with mechanical coding or with RFID initiators for confusion-free coupling to ensure safe filling, loading and transfer.

Equipped in this way, the quick couplings reliably counteract the consequences that may be caused by the confusion of lines with aggressive or unhealthy media, thus enabling fault-free, safe and quick separation and connection. The sophisticated clean break technology reduces both residual leaks when separating, as well as air entry when coupling, down to a physical minimum. The robustly designed mechanical guidance of the CN couplings offers simple handling when coupling and, with the help of a swivel-mounted connecting piece, reduces the wear of the media interface caused by hose torsion. WALTHER also offers ring grips to further increase ergonomics.
