Brand: K-Rain SKU: 4606
Product Overview
The K-Rain 4606 is a six-outlet 4000 Series indexing valve with a factory-installed six-zone cam. It distributes water sequentially through all six outlets as the upstream pump or control valve cycles off and on. This makes it the full-capacity configuration of the 4000 Series six-outlet body.
The ABS polymer valve has a 1¼-inch slip inlet and six 1-inch slip outlets. K-Rain lists operation at approximately 10 GPM minimum flow and pressures from 25 to 75 PSI. It can automate residential or small-commercial irrigation from a single controlled supply and may also be used in approved pump, city-water, wastewater, or effluent systems.
The valve advances hydraulically, so each cycle must stop water completely before restarting. Proper vertical installation, sufficient flow, correct pressure, and balanced outlet conditions are critical. Because all six outlets are active, each lateral must be connected and designed for the intended sequence. A different compatible cam can reduce the valve to two, three, four, or five operating zones if the system is later changed.

Frequently Asked Questions
Does the 4606 include the six-zone cam?
Yes. It is the complete six-zone configuration.
Can it operate fewer than six zones?
Yes, with the correct replacement cam and corresponding outlet piping changes.
Does it require six electrical valves?
No. The valve hydraulically indexes among its six outlets.
