Brand: K-Rain SKU: 4605
Product Overview
The K-Rain 4605 is a six-outlet 4000 Series indexing valve preconfigured for five-zone operation. Its installed cam advances water through five selected outlets each time the upstream water source cycles off and on, leaving one physical outlet outside the sequence. The six-outlet body provides the connection layout required for systems that need more than the four zones available from the 4400 platform.
The valve uses a 1¼-inch slip inlet and six 1-inch slip outlets in an ABS polymer body. K-Rain lists the 4000 Series for approximately 10 GPM minimum flow and 25 to 75 PSI. It is used in residential and small-commercial irrigation and can also serve compatible pump, city-water, onsite wastewater, and effluent distribution systems where local rules allow.
No separate downstream solenoid is required at each outlet. The internal stem-and-disc assembly advances when flow stops completely and then resumes. Proper vertical installation, adequate hydraulic capacity, balanced downstream restrictions, and sufficient off time are necessary. The valve can be converted to three, four, or six operating zones using the correct six-outlet cam.

Compatibility and Installation Notes
Identify the five active outlets before connecting the system. Install vertically, use approved solvent-weld procedures, and allow the valve to drain and depressurize fully between cycles. Confirm the 1-inch outlet size and the flow demand of each zone before ordering.
Frequently Asked Questions
Why does a five-zone valve have six outlets?
The installed five-zone cam leaves one of the six physical outlets outside the sequence.
Can it be converted to six zones?
Yes. Install the compatible P6107066 six-zone cam and connect the remaining outlet.
Are the inlet and outlet sizes the same?
No. The inlet is 1¼ inches and each outlet is 1 inch.
Why Buy the K-Rain 4605 from Big Frog Supply?
The 4605 arrives with the correct five-zone cam already installed in the six-outlet body, avoiding a separate configuration step. Big Frog Supply also carries the adjacent three-, four-, and six-zone cams plus the service parts needed for future repair or expansion.
