K-Rain 4404 4-Outlet Indexing Valve for 4-Zone Operation
Brand: K-Rain | SKU: 4404
Product Overview
The K-Rain 4404 is a 4-outlet 4000 Series indexing valve configured for 4-zone operation. The installed cam uses all 4 outlets sequentially as the upstream pump or control valve shuts off and restarts.
This is the full four-zone configuration of the 4000 Series four-outlet platform, intended for systems that need every outlet in the rotation.
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 4404 use every outlet?
Yes. The installed four-zone cam advances through all four physical outlets.
Can it be changed to fewer zones?
Yes. A compatible two- or three-zone cam can be installed with the correct piping changes.
What controls the zone change?
The valve advances when water flow stops completely and then restarts.
