ABSTRACT:
A flow distribution and control device for connection to a fluid supply includes an inlet assembly and an outlet assembly. A valve member is positioned in a flow path between the inlet and outlet assemblies and moves to an open position in response to increased differential pressure between the inlet and outlet assemblies. Discharge holes selectively permit communication between the inlet and outlet assemblies when the valve member is in the open position. A cylindrical flow distribution ring seated in the outlet assembly defines a radial collector gap that has a larger diameter than that of adjacent radial interior surfaces of the ring and inlet assembly. The flow path is open when the valve member is in an open position and at least one of the discharge holes is exposed to the collector gap.
