Walther-Präzision presents its new “DD” quickcoupling series. These innovative clean-break couplings made of high-quality stainless steel have been specially developed to meet the Pressure Equipment Directive for aggressive fluids or gases in media group I in high-pressure and hightemperature applications. A perfect match that meets the even more demanding requirements of HPHT chemistry.
The maximum operating pressure depends on the respective operating temperature (Tmax = 250 °C) and the nominal diameter used. It reaches up to 350 bar. As a result, quick couplings can now be used for increased process safety and improved productivity on thermal- and pressure-loaded lines, which were previously equipped inefficiently with flange connections.
The DD series does not only offer increased productivity in terms of time savings when quickly disconnecting and connecting or maintaining the line systems: The extremely smooth surfaces allow quick and easy cleaning, for example. Furthermore, high-quality and replaceable seals on the couplings ensure a long service life and high endurance with minimal maintenance required even under differential pressures.
Atex-certified quick couplings from the DD series offer maximum safety for the operator and for the environment, as they are entirely splash-free and only show the lowest of physically unavoidable residual leakage when decoupling.
