Abstract
A valve includes a valve chamber and at least two flaps capable of opening to provide an outlet for fluid or closure to block fluid flow. In or immediately adjacent to the valve chamber are catch mechanisms for controllably latching flap elements in an open or a closed position. In normal operation, the flaps open and close at a certain oscillation frequency in response to oscillatory fluid pressure differentials. Since the flap elements move, oscillations eventually bring the flap elements into catchment range of catch mechanisms capable of holding the flaps open or closed.
