ABSTRACT A flow control device comprising a spindle having a disk at its lower end and a handle at its upper end and spring-biased to bring the disk into pressing contact with a disk seat within a case, a closure having a top wall, and at least one rollable member resting on the upper surface of the closure top wall and mounted on the spindle at an upper end portion thereof projecting upward from the upper surface of the closure top wall. The closure is formed in the upper surface of its top wall with a lower recessed portion for the rollable member to partly fit in, an upper recessed portion for the rollable member to partly fit in and a slanting guide face between the two recessed portions. The roll- able member is movable by the rotation of the handle to partly fit into the lower recessed portion to thereby hold the disk in pressing contact with the disk seat or to partly fit into the upper recessed portion to thereby hold the disk away from the disk seat.
