Annotation:
The configuration is considered of direct-action electrohydraulic valve ensuring wider operating range of the working fluid flow rate and pressure. The mathematical model of electrohydraulic valve is presented and the computational investigations of dynamic characteristics were performed. As a result of the investigations, the calculated dependencies were obtained that enable evaluating the design parameters impact on valve opening time when designing an electrohydraulic valve of given type.
