The F-79 Intelligent Head is designed to work with various types of water conditions. The advanced design incorporates a microcomputer control that analyzes real-world operating conditions and performs regeneration automatically. The unique control valve features highly polished, high density, ceramic discs that are the heart of the Rotary Pro Design. The patented ceramic disc design incorporates one fixed and one moving disc, which rotates through positions to align channels creating five different fluid pathways. These five pathways, or stages, are: Service, Backwash, Brine & Slow Rinse, Brine Refill, and Fast Rinse. This proprietary design represents a significant advance beyond traditional water treatment system control valves, which traditionally rely on complex valving and a high number or parts, that are vulnerable to wear and failure during operation. The breakthrough design of the advanced F-79 Rotary control valve provides simple installation, operation and maintenance.
