It is installed on the water inlet piping in sealed heating systems and its main function is to maintain the pressure of the system at a set value, automatically filling up with water as required. The valve is pre-adjustable, meaning it can be set to the desired pressure value before the system charging phase. After installation, during the filling or topping-off phase, the water feed will stop when the set pressure is reached. This valve fills 50% faster than other valves. There are no levers to flip or valve to close. Pre-assembled with the 573 series backflow preventer, the AutoFill™ combo features an atmospheric vent which is designed to protect drinking water systems from return flow, caused by back-siphoning or backpressure, of contaminated fluids. The 573 series has been specifically certified to standards csa B64.3 and ASSE 1012.\u003c\/p\u003e\u003cul\u003e\n\u003cli\u003ePre-adjustable automatic filling valve with backflow preventer\u003c\/li\u003e\n\u003cli\u003eBrass body\u003c\/li\u003e\n\u003c\/ul\u003e\u003ch4\u003eSpecifications\u003c\/h4\u003e\u003ctable\u003e\n\u003ctr\u003e\n\u003ctd\u003ePressure Gauge Scale\u003c\/td\u003e\n\u003ctd\u003e0 to 60 psi\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd\u003eConnection Type\u003c\/td\u003e\n\u003ctd\u003ePress\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd\u003eMaterial\u003c\/td\u003e\n\u003ctd\u003eBrass\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd\u003eTemperature Rating\u003c\/td\u003e\n\u003ctd\u003e150 deg F\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd\u003eNominal Size\u003c\/td\u003e\n\u003ctd\u003e1\/2 in\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd\u003eFilter Mesh Size\u003c\/td\u003e\n\u003ctd\u003e#35\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd\u003eSeries\u003c\/td\u003e\n\u003ctd\u003e573 Series\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd\u003ePressure Rating\u003c\/td\u003e\n\u003ctd\u003e175 psi\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd\u003eDimensions\u003c\/td\u003e\n\u003ctd\u003e11-1\/8 in L\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003c\/table\u003e","brand":"Caleffi","offers":[{"title":"Default Title","offer_id":51320200265953,"sku":"CAL573006A","price":139.82,"currency_code":"USD","in_stock":false}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0800\/0451\/4017\/files\/Caleffi_573006A.jpg?v=1794346166","url":"https:\/\/remsco.com\/products\/cal573006a","provider":"Remsco","version":"1.0","type":"link"}
