K-Rain 4606 6-Outlet Indexing Valve for 6-Zone Operation

K-Rain 4606 6-Outlet Indexing Valve for 6-Zone Operation

Brand: K-Rain | SKU: 4606

Product Overview

The K-Rain 4606 is a 6-outlet 4000 Series indexing valve configured for 6-zone operation. The installed cam uses all 6 outlets sequentially as the upstream pump or control valve shuts off and restarts.

This is the full six-zone configuration for the lightweight 4000 Series six-outlet body, used when a single upstream supply must sequence all six laterals.

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

Does the 4606 include the six-zone cam?
Yes. It is configured for six operating zones.

Can it operate fewer than six zones?
Yes, but it requires the correct replacement cam and corresponding outlet-piping changes.

Are the inlet and outlets the same size?
No. The inlet is 1¼ inches and the six outlets are 1 inch.

Why Buy the K-Rain 4606 from Big Frog Supply?

Big Frog Supply separates the 4606 from the smaller four-outlet 4000 valves and lists its six-outlet layout, connection sizes, and operating requirements so teams can confirm the correct replacement before ordering.
