Danfoss 003L6122 Auto By-Pass Valve AVDO 20mm 22mm Constant Flow Control\n\nThe AVDO range of automatic bypass valves can be used as either differential pressure controls or to provide a minimum flow through a system. Many boiler manufacturers are now insisting that a bypass be fitted in all installations to ensure that the volume of water circulating through the boiler does not fall to below a predefined minimum, regardless of the load on the system. Recognising the energy efficiency advantage of such controls the Building Regulations now require in both new-build and boiler replacement contexts, where a bypass is specified by the boiler manufacturer, that an automatic bypass is fitted. Automatic bypass valves improve system efficiency by opening only when there is a need to bypass water, this usually occurs at times of part load when radiator thermostats in the system are partly closed and water flow around the boiler is restricted. In addition to ensuring adequate flow around the .
