A valve assembly has a first ceramic valve member having a flat valving surface. An aperture open to the valving surface is provided through the valve member. The valve assembly further has a tubular valve member having an aperture therethrough, and an annular valving surface adjacent to the valving surface of the other valve member. The apertures through the respective valve members are moved into and out of registry with each other by relative movement therebetween. Preferably, a valve body is provided having a large bore accepting the first valve member and a small bore accepting the tubular valve member. The apertures are movable into and out of registry by rotation of the first valve member within the large bore.
