The spool displacement of a directional control valve can be considered as the standard signal for the measurement of its bandwidth frequency. When the spool displacement is not available, the metering-orifice system is suggested in this study as an alternative way to measure the - 3 dB amplitude-ratio bandwidth frequency of the hydraulic directional-control valve. The amplitude ratio of the metering-orifice pressure can be adjusted to equal that of the spool displacement through the controlling of the metering-orifice opening area. A series of experiments were conducted to verify the effectiveness of the metering-orifice system. The metering orifice was confirmed as adequate for the measurement of the - 3 dB amplitude-ratio bandwidth frequency.

The spool displacement of a servo valve can be considered to be the standard signal to measure the bandwidth frequency of servo valves. When the spool displacement is not available, the metering orifice system is suggested as an alternative way to measure the – 3 dB amplitude ratio bandwidth frequency of the hydraulic servo valve in this study. The amplitude ratio of the metering orifice pressure can be adjusted to be the same as that of the spool displacement by controling the opening area of the metering orifice. A series of experiments were conducted to verify the effectiveness of the metering orifice system. The metering orifice was found to be good enough to measure the – 3 dB amplitude ratio bandwidth frequency.
