Abstract: Focusing on reverse pneumatic pressurereducing valve (PRV), we develop a dynamic mathematical model in this paper. The PRV dynamic characteristic of working process is simulated and the different parameters that influence the PRV’s response characteristic are analyzed. Then, by adopting linearization technique, the state space model (SSM) of PRV is established. The effects of main parameters on valve stability are obtained. The method that can improve the valve response characteristic and stability performance is also presented.

Key words: pressurereducing valve, response characteristic, stability
