This paper deals with a methodology for measuring and evaluating the static characteristics of control valves, with specifying a recommended measurement chain. This method enables measuring and evaluating the dependence of pressure drop on flow and flow coefficients depending on the type of fluid, temperature and viscosity also if the measurements were made at a different temperature and viscosity. This method extends of the possibility of using of these characteristics in the design work on hydraulic components in various areas of operation.
