UWS filling combination 300920
The UWS BA DN 15 filling combination is used for the automatic filling of closed hot water heating systems . The integrated BA system separator, compliant with DIN EN 1717, reliably prevents backflow of heating water into the drinking water network. This allows for a direct fixed connection of the heating system to the drinking water installation in accordance with EN 1717.
The unit features inlet and outlet shut-off valves , a pressure reducer with a pressure gauge , and an integrated stainless steel mesh strainer . The pressure reducer ensures a constant and correctly set system pressure.
The output pressure is adjustable from 1.5 to 4 bar and is factory preset to 1.5 bar . The robust housing is made of forged brass and comes with screw connections on both sides and a thermal insulation shell .
