Water system safety valve GENO®-DK 2

differential

GENO®-DK 2 (nominal connection diameter DN 15-50) are system separators according to construction design BA of DIN EN 12729. The system separator,is a safety device to be installed in water pipes if special with drawal points or appliances are connected to the drinking water supply. The Euro-system separator prevents the back-flow, back-pressure and backsuction of modified drinking water into the drinking water network. They can, as per DIN EN 1717, be used to protect vulnerable drinking water plants and systems up to and including hazard class 4 and replace pipe separators EA 1 and EA 2. GENO®-DK 2 are made of brass up to dimension R 1¼", and red bronze as of dimension R 1½". The safety devices are suitable for operating temperatures of up to 65°C at PN 10 bar. They work according to the 3-chamber system, subdivided into an inlet pressure zone, central pressure zone and rear pressure zone. When the pressure is released, the central pressure zone is pressure-free and is opened to the atmosphere. The system separators have, among other things, water inlet and outlet connecting pieces, water meter screw connections, non-return valves and connection pieces for inspection pressure gauges.
