Abstract

A flush valve includes a valve housing defining a fluid passageway between a fluid inlet and a fluid outlet. The fluid passageway includes a diaphragm valve seat disposed between the fluid inlet and the fluid outlet. The flush valve additionally includes a diaphragm assembly including a diaphragm and a disc. The diaphragm includes a primary opening and a bypass opening. The primary opening receives the disc therein and the bypass opening allowing water under pressure supplied to the fluid inlet to pass from a fluid inlet side of the diaphragm into a chamber in the fluid passageway. The flush valve additionally includes a relief valve configured to selectively control fluid flow from the chamber to the fluid outlet. The relief valve comprises a stationary valve element and a rotatable valve element each having at least one opening and being rotationally positionable relative to one another to regulate fluid flow.
