Definition of Valve

Valve

A door; especially, one of a pair of folding doors, or one of the leaves of such a door.

One or more membranous partitions, flaps, or folds, which permit the passage of the contents of a vessel or cavity in one direction, but stop or retard the flow in the opposite direction; as, the ileocolic, mitral, and semilunar valves.

One of the pieces into which a capsule naturally separates when it bursts.

One of the two similar portions of the shell of a diatom.

A small portion of certain anthers, which opens like a trapdoor to allow the pollen to escape, as in the barberry.
