K-Rain 4605 6-Outlet Indexing Valve for 5-Zone Operation

K-Rain 4605 6-Outlet Indexing Valve for 5-Zone Operation

Brand: K-Rain | SKU: 4605

Product Overview

The K-Rain 4605 is a 6-outlet 4000 Series indexing valve configured for 5-zone operation. The installed cam advances through 5 selected outlets and leaves 1 physical outlet outside the operating sequence as the upstream pump or control valve shuts off and restarts.

The six-outlet body provides the connection layout required for systems that need more than the four zones available from the 4400 platform while leaving one physical outlet out of the five-zone sequence.

Before ordering, confirm the outlet count, zone sequence, inlet and outlet sizes, available flow, operating pressure, and whether the installation requires separate backflow protection. Indexing valves depend on a complete interruption of water flow between cycles so the internal stem-and-disc assembly can reset and advance.
