Abstract
A valve assembly for controlling fluid flow to a tube connected to the assembly by shifting of a sleeve mounted on the assembly. When the sleeve is shifted into a shutoff position, a fluid path through the assembly is completely occluded by a closure element in the sleeve. As the sleeve is rotated away from its shutoff position, the fluid path is gradually opened.
