SYR System Separator 6610 LF DN40, R1 1/2

The BA 6610 In-line system disconnector is a compact safety device according to DIN EN 1717, group B, with controlled separation (three-chamber system). It corresponds to the installation type BA defined therein and can therefore be used for protection up to and including fluid category 4. Its purpose is to prevent back-siphonage or backflow of non-potable water into the public drinking water network. The BA system disconnector covers a wide range of applications (e.g. printing companies, chemical and food processing plants, laboratory and medical technology).
The BA 6610 system disconnector contains all components specified in DIN EN 1717 and is designed as a 3-chamber system with controllable upstream, midstream and downstream pressure zones. In addition, it is equipped with an integrated strainer. Each pressure zone is fitted with ball valves, enabling the safety devices to be checked by pressure measurement. The system disconnector consists of 2 series-connected backflow preventers (RV), which are equipped with a ventilated central zone. If no water is drawn off, the inlet and outlet side RVs, as well as the drain valve, are closed. In the event of back-siphonage, the inlet pressure drops. The drain valve opens at the latest when the differential pressure between the upstream and midstream pressure chambers has dropped to 0.14 bar.
