K-Rain 4402 4-Outlet Indexing Valve for 2-Zone Operation
Brand: K-Rain | SKU: 4402
Product Overview
The K-Rain 4402 is a 4-outlet 4000 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.
This 4000 Series valve can automate two downstream irrigation zones from one controlled water source without wiring a separate electric valve at each zone. The four-outlet body also gives service flexibility if the system is later reconfigured with a compatible cam.
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. Use compatible solvent-weld materials, allow full cure time, and make sure the upstream controller creates a full off cycle. Confirm each zone’s flow demand matches the available supply.
Frequently Asked Questions
Why does a two-zone valve have four outlets?
The four-outlet body uses a two-zone cam, so only two outlets are part of the operating sequence.
Can the zone count be changed later?
Yes. A compatible three- or four-zone cam can be installed if the piping layout supports the new sequence.
Does the valve require electricity?
The indexing valve itself is water operated. The upstream pump or master valve may still be controlled electrically.
Why Buy the K-Rain 4402 from Big Frog Supply?
Big Frog Supply organizes the 4402 by its exact two-zone cam, four-outlet body, connection sizes, and operating requirements so homeowners, contractors, and maintenance teams can compare it against the adjacent 4403 and 4404 models before ordering.
