The AVDO self-acting constant flow controls are used to maintain a minimum flow rate (e.g. through a low water content gas boiler) or to control differential pressure in a heating system. The closing of radiator or zone valves due to reduced heating demand may result in low flow and increased system differential pressure (potentially dead heating pumps). AVDO valves open with a falling system load and allow flow through a bypass line whenever the differential pressure through the valve exceeds set point; ensuring a minimum flow rate or a system differential pressure at minimum system load.Danfoss 003L602502 AVDO Series Automatic By-Pass Valve Features:
