The BiWorld Automatic Bypass Valve - 22mm provides a constant minimum flow throughout a central heating system, as well as balancing distribution of water flow to thermostatic radiator valves. This prevents unnecessary cycling of the boiler. This valve helps the elimination of noise, maintains pump head pressure at a constant level and is perfect for low water content systems.
