The BA 6628 Plus system filling valve (pressure gauge with double indication) is used to automate the filling of water heating systems. Type BA anti-drain valve, in accordance with PN EN 1717, protects against backflow of heating water into the drinking water system. In the event of backflow - a drop in inlet pressure, the emptying valve opens at the latest when the differential pressure between the first and second chambers drops below 0.14 bar. The BA kombi 6628 Plus system filling valve has all the parts required by PN EN 1717 for direct connection of heating and drinking water systems, for fluids up to and including category 4. The built-in pressure regulator maintains a constant output pressure set on it, ensuring the required conditions for filling and during normal operation of the heating system. The latest version of the BA-class filling valve has a pressure gauge with an indication of the pressure before and after the valve (the pressure in the central heating system), shut-off valves on the inlet and outlet, as well as additional stubs for connecting a measuring device and measuring the differential pressure. The whole is enclosed in protective foam insulation. Net weight: 1.44 kg. Input pressure: 10 bar maxOutput pressure: 1.5 - 6 bar. Operating temperature (input): 30°C max. Operating temperature (output): 65°C max
