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.

Frequently Asked Questions
Why does a five-zone valve have six outlets?
The installed five-zone cam leaves one of the six physical outlets outside the sequence.
Can it be converted to six zones?
Yes. Install the compatible six-zone cam and connect the remaining outlet.
Are the inlet and outlet sizes the same?
No. The inlet is 1¼ inches and each outlet is 1 inch.
