Abstract: A flow control valve includes a body portion including a first end, a second end and an axially extending passageway. A metering valve is included that is axially moveable under the influence of fluid pressure from a rest position to a flow restricting position. In the flow restricting position, the metering valve can restrict the flow of fluid through the axially extending passageway. The metering valve includes an upstream portion and a downstream portion. The upstream portion has a flattened top spherical shape. A biasing device is provided that normally biases the metering valve in the rest position, and for provides resistance to movement of the metering valve to the flow restricting position.

Abstract: A valve is provided for use in a domestic water re-circulation system The valve has a unitary body member that includes an upstream end and an upstream portion disposed adjacent to the upstream end. The body member also includes a downstream end and a downstream portion disposed adjacent to the downstream end; and a middle portion disposed between the upstream portion and the downstream portion. A radially outwardly facing outer wall and a radially upwardly facing inner wall exist. The radially inner facing wall defines an axially extending passageway extending between the upstream end and the downstream end, and through the upstream portion, middle portion and downstream portion of the body. The axially extending passageway includes a corresponding upstream end, a downstream end, an upstream portion, a middle portion and a downstream portion. The body further includes a radially extending controller port and a radially extending flow limiter port in fluid communication with the axially extending passageway.
