The dynamic characteristics of the poppet valve with series restriction chokes, which used as a directional/flow control valve, have been studied. By using the mathematical model, which includes several nonlinear terms, the dynamic response of the valve was precisely estimated. It was also shown that the volume of the load circuit considerably affects the dynamic response of the valve. A stable condition of the circuit was obtained from the linearlized equations of the model, and its validity was confirmed by the experimental results.
