FAUCET VALVE WITH DIAGONAL O-RING SEAL Abstract of the Disclosure 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 a major portion 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.
