A fine metering valve having a deflectible beam and means for deflecting the beam adjustably in close spaced juxtaposition to a valve port thereby to vary the rate of fluid flow therethrough. A displacement reduction means is utilized in providing the deflection of the beam to give high accuracy in the metering of the fluid flow. The deflecting means may be manually operated or automatically operated, as desired. Means are provided for positively displacing the beam to fully close the valve when desired.
