A proposal for a new methodology to determine inner authority of the control valve in the heating system

This paper presents and discusses a proposal for a new methodology to determine the control valve inner authority, which is one of the basic parameters deciding about the control valve regulation capacity. Experimental verification is also carried out for selected control valves using the proposed concept and the alternative analytical methodology presented in recent years by Pyrkov. A comparison of the results is presented. It is shown that the proposed methodology gives results consistent with experimental data, whereas the results obtained using previously known methods can be substantially different from them.
