With the aim to insure the better linear degree of electro-pneumatic proportional valve and raise the response speed of its speed on-off valves, a doubled-voltage control mode with high voltage driving and low voltage PWM was proposed. In the mode, the high voltage (24 V) could shorten the open time, and the low voltage PWM (6 V) could reduce the power loss and shorten the closing time according to the pulse width controlled by PID. An electro-pneumatic proportional pressure valve controlled by a MCU ATmega8L was designed based on the mode. The tested results show that, using the mode of high voltage driving and low voltage PWM, the open time of the high speed on-off valve is reduced to 0.8 ms, the turnoff time is 0.3 ms, and the total power consumption is 2.18 W. 
