Flow Straighter for Metered Valves 14613 used on most residential Fleck Metered Valves.
Includes Fleck 5600, 9000, 9100, 2500 and 2510.
Rainsoft part number cross reference = 17692
INSTALLED on the outflow port of the Valve Body ( or in meter assemblies ), and I've seen them pointed both in or out.
It should be ( will work best ) if pointed outward ( nozzle pointed towards the impeller of the meter ).
The PURPOSE of the flow straightener is to help the meter turbine / impeller "Move" when the water flow rate is low.
Straightening the flow = concentrating the flow.
The system will "work" without a straightener, but will not be as accurate ( counts all the water used at lower flow rates ).
