Cam, Brine, Rainsoft P/N 17501
Used in some, but not all, newer Rainsoft Valves ( that is based on the Fleck 5000 Valve Body design ).
Most Rainsoft do use this one ( 17501 ),
And it has a shorter shaft and different Cam contact points then similar Fleck PN 18228.
When this Cam breaks, it could mean it is time to replace the Brine Valve ( 60032 ).
