Pneumatic high-speed solenoid valve is a very important comment for automation control system. With the rapid development of industry its quality requirements are getting higher and higher. The traditional method is manual measurement or semi-automatic measurement, and comprehensive evaluation of solenoid valve parameters is lacked. To solve the problem of measuring solenoid valve at present, the PC controlled experimental tester for solenoid valve based on high speed data acquisition was built up. It can measure these parameters: dynamic characteristic, sealing performance, the minimum pilot pressure test, fatigue life test. To verify the system accuracy, a dynamic simulation model of solenid valve based on Matlab/Simulink was designed. This model can provide a basis for the design of solenoid valve. The solenoid valve of type QVT307 was measured on the experimental device, and the applications software was programmed by VC++, which had the function of A/D high-speed data acquisition. The results show that characteristic parameters of the solenoid valve can be judged well by this system. Data acquisition rate can be up to 0.1ms, and the pressure resolution is 0.1Kpa.
