23YControl functionsWith the Belimo Energy Valve™, various control variables can be allocated to the positioning signal, depending on the respective requirements. 1. Position controlIn this setting, the positioning signal is assigned to the opening angle of the valve (e.g. Y = 10 V <–> α = 90°). This results in pressure-dependent operation similar to that of a conventional valve.2. Flow controlThe positioning signal directly requires a defined water quantity (e.g. Y = 10 V <–> V' = 80 l/min). The valve unit selects the opening angle automatically so that the requested water quantity is available. Differential pressure fluctuations are thus automatically compensated for by the Belimo Energy Valve™ –> pressure-independent operation.3. Power control
