{"product_id":"syr-systemtrenner-stba-typ-100-dn15-r-3-4","title":"SYR backflow preventer STBA Type 100, DN15 R 3\/4","description":"The BA STBA 100 system disconnector is a compact safety device according to DIN EN 1717, Group B, with controlled disconnection (three-chamber system). It corresponds to the BA installation type defined therein and can therefore be used for protection up to and including fluid category 4. Its task is to prevent the backflow or backsiphonage of non-potable water into the public drinking water network. The BA system disconnector covers a wide range of applications (e.g., printing plants, chemical and food processing plants, laboratory and medical technology).\u003cbr\u003eThe BA system disconnector complies with DIN EN 1717 and the components specified therein and is designed as a 3-chamber system with controllable inlet, intermediate, and outlet pressure zones. Additionally, it is equipped with an integrated strainer. Each pressure zone can be fitted with test valves (accessory 6625.15.902), thus allowing for monitoring of the safety devices by pressure measurement. The system disconnector consists of 2 series-connected backflow preventers (RV), which are equipped with a ventilated intermediate zone. If no water is drawn, the inlet and outlet side RVs, as well as the drain valve, are closed. In the event of backsiphonage, the inlet pressure drops. The drain valve opens at the latest when the differential pressure between the inlet and intermediate pressure chambers has dropped to 0.14 bar.\u003cbr\u003eTechnical data:\u003cbr\u003e Operating pressure: max. 10 bar\u003cbr\u003e Operating temperature: max. 30 °C (inlet), max. 65 °C (outlet)\u003cbr\u003e Ambient temperature: 5 °C - 40 °C\u003cbr\u003e Installation position: any, if drain funnel is downwards\u003cbr\u003e Medium: Drinking water\u003cbr\u003e Flow rate: 1.8 m³\/h at ?p 1.5 bar.\u003cbr\u003e Connection size: DN 15","brand":"Sasserath","offers":[{"title":"1","offer_id":56539180499330,"sku":"WCW-0099559-001","price":208.99,"currency_code":"EUR","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0928\/3675\/7890\/files\/4_6_8_5_468527aaf0ea1f4c53ffb6085d2de61c325aec85_wcw_0099559_gl_image2_converted_500x500_syu_662515000_jpg.jpg?v=1775704803","url":"https:\/\/shop.we-connect.work\/en\/products\/syr-systemtrenner-stba-typ-100-dn15-r-3-4","provider":"weconnectwork","version":"1.0","type":"link"}
