Between 52°C and the set point of 57°C, the valve starts to close. When the set point temperature has been reached, a minimum volume flow is continuously flowing through the circulation system. If the storage temperature is further increased to temperatures greater than 70°C to effect disinfection, the valve increases the flow.\u003cbr\u003e\u003c\/p\u003e\n\u003ch5\u003eSpecification\u003c\/h5\u003e\n\u003cp\u003eTaper threaded to BS EN 10226-2\u003c\/p\u003e\n\u003ch5\u003eDatasheet\u003c\/h5\u003e\n\u003cp\u003e\u003cstrong\u003e\u003c\/strong\u003e\u003ca href=\"https:\/\/cdn.shopify.com\/s\/files\/1\/0812\/3452\/6525\/files\/hattesley-Fig-2900-2910-TCV-datasheet.pdf?v=1758019102\" title=\"Hattersley Fig 2900 PN16 Thermal Circulation Valve Datasheet\"\u003eHattersley Fig 2900 PN16 Thermal Circulation Valve Datasheet\u003c\/a\u003e\u003c\/p\u003e\n\u003ch5\u003eNotes\u003c\/h5\u003e\n\u003cp\u003eThis item is the equivalent of the Crane D2890 Thermal Circulation valve\u003c\/p\u003e","brand":"Hattersley","offers":[{"title":"DN15 - 004B02900JW","offer_id":53084615180624,"sku":"HA-004B02900JW","price":144.27,"currency_code":"GBP","in_stock":true},{"title":"DN20 - 006B02900JW","offer_id":53084615213392,"sku":"HA-006B02900JW","price":207.08,"currency_code":"GBP","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0939\/2344\/3024\/files\/fig2900-TCV-cutout-BF.png?v=1780050440","url":"https:\/\/industrialvalveoutlet.com\/products\/hattersley-2900-pn16-thermal-circulation-valve","provider":"Industrial Valve Outlet","version":"1.0","type":"link"}
