ABSTRACT:
A new flow control valve comprises valve openings, having valve seats opened and closed by poppets, provided in fluid passages extending from an inlet port to an outlet port in the valve body, and a control mechanism to produce a changeover of pilot pressure and a setting of time lag in response to a pulse signal of variable frequency from a pulse oscillator provided for a pilot control section, the openings at the valve seats being opened and closed through the control of the frequency as well as the setting of the time lag, so that a flux of the fluid can be controlled exactly.
