Abstract
An improved faucet valve utilizes a static diagonal sealing ring which coacts with a control member cylindrical flow control portion having a tapered lower end portion in a relationship that provides: substantially 180 degrees of control member rotation from full open to full close and vice versa, with metering of fluid flow taking place over a major portion of the control member rotational range; contact of nearly all of the sealing ring inner periphery with the control member flow control portion during initial opening and final closing stages when differential pressure is high, so there is no tendency for the sealing ring to be forced out of its grooves; the diagonal sealing ring does not move past a fluid discharge opening or vice versa, so the diagonal sealing ring is not subjected to chafing which would result in excessive wear.
