K-Rain 13003-CV MiniPro 4-Inch Rotor with Check Valve

K-Rain 13003-CV MiniPro 4-Inch Rotor with Check Valve

Brand: K-Rain | SKU: 13003-CV

Product Overview

The K-Rain 13003-CV is a compact 4-inch MiniPro gear-driven rotor with a factory-installed check valve. It provides adjustable rotor coverage for smaller lawns and landscape zones while helping reduce low-head drainage from sprinklers installed at lower elevations.

The rotor uses a 1/2-inch female NPT inlet, five interchangeable nozzles, and top arc adjustment from 40° to 360°. Before ordering, confirm the exact CV suffix, connection size, available dynamic pressure, total zone flow, required radius, head spacing, and elevation difference. The check valve does not correct a leaking control valve or broken pipe.
