DU144 Automatic Bypass Valve

DU144 Automatic Bypass Valve
The DU144 automatic bypass valve controls water flow in the heating circuit according to the water pressure across it and is used to maintain a minimum flow rate through the boiler and to limit ciruclation pressure when other water paths are closed.
