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 fi lling up with water as required. After installation, during the fi lling or topping-off phase, the water feed will stop when the set pressure is reached. This valve fi lls 50% faster than other valves. There are no levers to fl ip or valve to close. Perfect to built and maintain pressure in a water or glycol radiant floor heating system Function The automatic fi lling valve is a device consisting of a pressure reducing valve with compensating seat, visual system pressure setting indicator, an inlet fi lter, anti-scale internal parts, a shut-off valve (round knob on bottom) and a check valve. 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 fi lling 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 fi lling or topping-off phase, the water feed will stop when the set pressure is reached. This valve fi lls 50% faster than other valves. There are no levers to fl ip or valve to close.","brand":"My Store","offers":[{"title":"Default Title","offer_id":54922399088853,"sku":"P356810445996301215","price":26.99,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0829\/5016\/0597\/files\/542F51FD-26DD-C007-C826-70798A556804.jpg?v=1789210173","url":"https:\/\/viraria.shop\/products\/caleffi-573002a-1-2x22-npt-inlet-bfp-autofill_5ab7b7ca","provider":"My Store","version":"1.0","type":"link"}
