In this paper, a new isothermal tank test circuit composed of two tanks and a new data-processing algorithm called Cbm method are proposed to measure the flow-rate characteristics of some pneumatic valves. The double-tank circuit is used to test some solenoid valves such as inner pilot solenoid, which the traditional isothermal discharge method can not apply to. And Cbm method changes the identification procedure of multivariable unconstrained optimal algorithm, which evidently improves the identification precision of critical pressure ratio and subsonic index.
