The quick couplings of the Clean-Break CN series from Walther Präzision meet the requirements of the directive
RL 2010/35/EU on transportable pressure equipment in conjunction with ADR/RID 2017 and DIN EN 14432:2014 for hazardous goods. This approval permits the use of CN quick couplings for transfer processes of liquid chemical products classified as hazardous into/from ADR/RID-approved containers as a secondary product shut-off valve downstream of the bottom valve and as a primary shut-off valve for peak use in road and rail vehicle tanks. In the case of tanks intended for the transport of these dangerous goods, the fittings can thus be used for filling and removal operations. The locking device is not placed in the flow coupling for hygienic and cleaning reasons. The CN couplings therefore have excellent hygienic properties, are easy to clean and SIP-compatible. All these quick coupling systems can be coupled against high differential pressures and are insensitive to transverse loads (forces acting at 90° to the axial direction).
