Abstract: In this paper, we have considered the application areas of proportional directional control valves and current problems associated with them. It has been found that in existing hydraulic control valves with electromagnetic control (or control from a linear motor), the position of the spool is a function of the current flowing in the solenoid of the electromagnet, and also depends on disturbances, in particular, on changes in the random nature of the hydrodynamic force. In this regard, the relevance of replacing the power circuit of the mechanical system (spool - spring - electromagnet, with a geometric circuit - stepper motor - screw pair - spring - spool) is emphasized.
