GENO-DK 2 (nominal connection diameter DN 15-50) are system separators according to construction design BA as per DIN EN 12729. The system separator, is a safety device to be installed in water pipes if special withdrawal points or appliances are connected to the drinking water supply. The Euro system separator prevents the back-flow, back-pressure and back-suction of modified drinking water into the drinking water network. In accordance with DIN EN 1717, it is possible to protect plants and systems endangering the drinking water up to and including hazard class 4 and replace EA 1 and EA 2 pipe separators.
The GENO-DK 2 are made of brass up to size R 1¼" and, as from size R 1½", of red brass. The safety fittings are suitable for operating temperatures up to 65°C at PN 10 bar. They operate according to the 3-chamber system with subdivision into upstream, intermediate and downstream pressure zones. When relieving, the middle pressure zone is depressurised and opened against the atmosphere. The system separators have, among other things, water inlet and outlet connections, water meter screw connections, non-return valves and connection points for test pressure gauges.
