Abstract
A valve is disclosed a valving member positioned in an internal valving cavity and operable to control a flow of water therethrough. The valving member includes a diaphragm and an insert. A passageway through the diaphragm communicates with a bleed slot, preferably a tapered bleed slot, and a scallop of the insert. The scallop cooperates with the diaphragm to form a bleed holes when the valving member is in a closed position. The diaphragm and the insert at least partially separate when the valving member is opened to expose the bleed slot and scallop. The diaphragm rolls up to contact the insert when the valving member is closed to create a wiping action to flush any trapped debris from the bleed slot.
