ABSTRACT:
An animal watering valve has an elastomeric diaphragm disposed in a bore of a housing upstream of a valve seat and having apertures formed therethrough for the passage of water. A valve stem has a head clamped between the diaphragm and the valve seat and a tail that is laterally deflectable to move the valve stem head relative to the diaphragm from a seated position. Upon moving it to an unseated position, the valve stem head pivots relative to the valve seat to permit water to flow out of the valve. At least portions of the flow aperture outlets in the diaphragm are located radially inwardly of and axially upstream of the upstream surface of the valve stem head.
