K-Rain Product Lines

K-Rain gear-drive rotors are known for a patented reversing mechanism built to keep turning reliably, even with dirty water. The line runs from the compact MiniPro and ProSport up to the PRO Plus, SuperPro, and the flagship RPS75, and most are arc-adjustable from the top.

K-Rain also makes electric solenoid valves and its well-known indexing valve, which sequences several zones from a single water source or pump — no electric controller required.

K-Rain FAQ

What makes K-Rain rotors different?

K-Rain rotors use a patented reversing mechanism designed to keep turning reliably even with dirty water, and most are arc-adjustable from the top. The RPS75 is the flagship model.

What is a K-Rain indexing valve?

An indexing valve automatically sends water to a different zone each time the supply turns on and off, so one pump or water source can run several zones in sequence — without an electric controller. It’s a common choice for pump-fed and lake- or well-supplied systems.

Are K-Rain rotors compatible with Hunter or Rain Bird systems?

Yes. K-Rain rotors install on standard female-threaded risers and swing joints, so they drop into most existing in-ground systems alongside other brands’ rotors.

Can I adjust the spray arc on a K-Rain rotor?

Yes. Most K-Rain rotors adjust from the top, letting you set the arc (the sweep angle) and fine-tune the radius with the nozzle — no need to dig up the head.
