Reduced pressure pneumatic valve design standard

basic performance:
( Regulating range: it refers to the reduced pressure pneumatic valve output pressure P adjustable range, meet the precision within the scope of this requirement. Regulating scope mainly related to pressure regulating spring stiffness.
　　( Pressure feature: it refers to the flow fixed value for g, caused by the input pressure fluctuation characteristics of the output pressure fluctuations. The smaller the output pressure fluctuation, the characteristics of vacuum pneumatic valve, the better. The output pressure must be less than the input pressure - Constant value was basically not changes over the input pressure.
( Flow feature: it refers to the input pressure - Timing, the output pressure changes along with the change of output flow g resistance. G when the flow changes, the output pressure changes as small as possible. Generally the lower the output pressure, which fluctuates according to the change of output flow. The design standard
