Abstract: PURPOSE: A flow metering valve assembly and a flow metering system are provided to reduce manufacturing cost by having the structure made of low components. CONSTITUTION: A differential pressure maintenance valve(120) opens and closes a supply flow path(140) due to the pressure difference of a first and a second fluid path and maintains the pressure difference of an inlet part and an outlet. A solenoid valve(130) opens and closes a path between the supply flow path and the outlet using a PWM(Pulse Width Modulation) mode. A pulse signal applying part applies pulse signals on a solenoid valve to proportion the amount of working fluid to the pulse width of the pulse signals. The pulse signal applying part applies the pulse signals in order to repetitively operate the solenoid valve.
