Auto Bypass Valve
Central Heating Automatic Bypass Valve 22mm
An Auto Bypass Valve is used to maintain a minimum, constant flow of water through your central heating system and boiler to reduce over-heating.
Where a central heating system has radiators fitted with Thermostatic Radiator Valves, this is particularly important. When Thermostatic Radiator Valves close, the flow of water reduces. When this happens the Automatic Bypass Valve will open to maintain the flow.
