K-Rain 6404 4-Outlet 6000 Series Valve for 4-Zone Operation
Brand: K-Rain | SKU: 6404
Product Overview
The K-Rain 6404 is a 4-outlet 6000 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 higher-capacity 6000 Series four-outlet platform, intended for installations 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.
