K-Rain 6605 6-Outlet 6000 Series Valve for 5-Zone Operation

K-Rain 6605 6-Outlet 6000 Series Valve for 5-Zone Operation

Brand: K-Rain | SKU: 6605

Product Overview

The K-Rain 6605 is a 6-outlet 6000 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.

This higher-capacity six-outlet valve supports larger piping and higher hydraulic demand than the 4000 Series while using a five-zone cam that leaves one physical outlet outside the 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.

Compatibility & Installation Notes

Identify the five active outlets before piping. Install vertically, use approved thread sealant and solvent cement, and allow water flow to stop completely between cycles. Confirm the supply, valve, and piping can deliver the selected zone flow at the required dynamic pressure.

Frequently Asked Questions

Why are there six outlets for five zones?
The five-zone cam leaves one physical outlet outside the operating rotation.

Can the valve be changed to six zones?
Yes. Install the compatible six-zone cam and connect the unused outlet.

Are the outlets 1 inch like some 4000 Series valves?
No. The 6000 Series outlets are sized for 1½-inch PVC connections.

Why Buy the K-Rain 6605 from Big Frog Supply?

Big Frog Supply identifies the 6605 as the five-zone version of the high-flow six-outlet 6000 platform and groups the important connection, flow, pressure, and cam details so buyers can compare it against the 6606 before ordering.
