In order to improve efficiency and flow characteristics of booster valve, one kind of pneumatic boost valve was proposed, which makes use of the expansion power, firstly, aiming to the process of pneumatic boosting valves, non-linear differential equations of pneumatic booster valves were set up, using the software MATLAB/simulink for modeling simulation. Secondly, According to the principle of simulation, input pressure-reduced pneumatic booster valve was studied experimentally; curves of exhaust flow and pressure of air in tank were got. Thirdly, a new energy consumption evaluation criterion in pneumatic system, air power, which determines the power transmitted by flowing compressed air, was briefly introduced. Finally, as a conclusion, it is clear that simulation and experimental results have a good consistency; flow of air exported by expansion energy-used pneumatic booster valve is larger than that by input pressure-reduced pneumatic booster valve; The efficiency of expansion energy-used pneumatic booster valve ranges from 73% to 81%, which is higher than that of input pressure-reduced pneumatic booster valve.
