Abstract: Aiming at optimization design on the control area of a piloted high speed onoff valve, dynamic analysis was performed to a piloted high speed onoff valve with a slide main valve, and the objective function was put forward to optimizing parametes of the main valve. As an example, a specific piloted large flow onoff valve was optimized according to the objecting function. In order to evaluation the performance of the optimized valve, a precision simulation model was established by AMESIM. Empirical method was applied to optimize the parameters of main valve based on the simulation model. The results obtained by simulation are consistent with the theory analyzed results. The results indicate that there exists an optimum control area with which the shortest switching time of main spool could be achieved.
