A conventional (pressure-dependent) valve is designed based on the kv value. For a given nominal flow rate, this depends on the differential pressure across the valve. In order to obtain sufficient quality of control, the valve authority Pv must also be taken into account for pressure-dependent valves. For a pressure-independent solution, such as the Belimo Energy Valve™, the design is greatly simplified. Due to the automatic adjustment of flow deviations, the Energy Valve always provides the required water quantity even with differen- tial pressure fluctuations and during partial load operation. Due to dynamic balancing, the valve authority amounts to 1.ConstantflowvolumeV'
