K-Rain 6402 4-Outlet 6000 Series Valve for 2-Zone Operation

K-Rain 6402 4-Outlet 6000 Series Valve for 2-Zone Operation

Brand: K-Rain | SKU: 6402

Product Overview

The K-Rain 6402 is a 4-outlet 6000 Series indexing valve configured for 2-zone operation. The installed cam advances through 2 selected outlets and leaves 2 physical outlets outside the operating sequence as the upstream pump or control valve shuts off and restarts.

The 6000 Series is K-Rain’s heavier-duty indexing-valve platform for higher-flow pump systems, high-flow city-water installations, and approved onsite wastewater or effluent applications.

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

Install vertically and identify the two active outlets before connecting laterals. Size the pump, valve, and piping for the selected zone demand, allow water flow to stop fully before the next cycle, and confirm any separate backflow requirements with local code.

Frequently Asked Questions

Why does a two-zone valve have four outlets?
The factory two-zone cam places only two of the four physical outlets into the operating sequence.

Can it be changed to three or four zones?
Yes. Install the compatible three- or four-zone cam and revise outlet piping as needed.

Is the built-in vacuum breaker always enough for code compliance?
No. Required backflow protection depends on the water source, application, and local code.

Why Buy the K-Rain 6402 from Big Frog Supply?

Big Frog Supply identifies the 6402 as the two-zone 6000 Series configuration and shows its higher-flow specifications, connection sizes, and cam relationship so buyers can compare it accurately against the 6403 and 6404.
