Runxin F63C3 Automatic Softening Head with 1″ Plastic Inlet, Output and Backwash Ports, 2.5″ Screw-In Port

Description

The Runxin F63C3 is an advanced metered (volumetric) automatic control valve specifically engineered for ion-exchange water softener systems. Unlike timer-based valves, the F63C3 triggers regeneration based on actual measured water throughput — only regenerating when the resin is truly exhausted, saving significant amounts of salt and water. Full automated regeneration cycle: Service — Backwash — Brine Draw — Slow Rinse — Brine Refill — Fast Rinse — Return to Service. The valve automatically blocks the outlet during regeneration to prevent raw hard water from entering supply. Features: LED dynamic display, keyboard auto-lock after 1 minute, long power outage indicator, interlock function, signal output, remote handling input, and pressure relief connector. All parameters fully programmable.
