Abstract: The action of the electropneumatic valve was divided into the electro motion and the pneumatic process.Dynamic models of these two processes were established. The response characteristic of the electro motion and the pneumatic process was simulated.Comparison with the cold test results showed that the dynamics models were correct.Effects of the pressure of control gas and voltage etc.on the electro motion are analyzed.

Key words: Electropneumatic valve;Electro motion;Pneumatic process;Dynamic models;Dynamic characteristic
