K-Rain 4000 Series 4 Outlet Indexing Valve 1-1/4 in. Slip | 4400

Product Overview

System shutdowns during the peak of summer heat can lead to rapid turf stress and costly crop loss. When an indexing valve fails, your crews face the pressure of diagnosing complex zone issues while water waste accumulates and project deadlines slip. With supply chain fluctuations causing unpredictable lead times, waiting until a valve cracks or sticks creates a liability for your business. Planning ahead and securing your inventory now ensures that your clients avoid dried-out landscapes and failed inspections during the high-demand irrigation season. Having these units on hand means you can provide immediate relief to your customers and keep your maintenance schedule moving without interruption.

The K-Rain 4000 Series Indexing Valve offers a significant technical advantage over multi-solenoid manifolds by simplifying the entire system architecture. Instead of wiring four separate valves and managing complex electrical bridges, this high-strength ABS unit uses a single station on your controller to cycle through four distinct zones. This design reduces the amount of wire required, minimizes the number of potential electrical failure points, and slashes labor hours during installation. By choosing a mechanical indexing solution, you give your firm a competitive edge through lower material costs and a more streamlined service profile for long-term maintenance contracts.

Installation Notes

For optimal performance, ensure the valve is installed vertically with the outlets pointing downward. All slip connections should be cleaned and primed before applying solvent cement to ensure a leak-proof seal. It is critical to match the pump flow rate to the valve's requirements to ensure the internal cam indexes properly between cycles. Always install a master valve or ensure the pump shuts off briefly between zones to allow the atmospheric pressure to reset the internal disc for the next sequence. Follow all local plumbing codes regarding backflow prevention when connecting to a potable water supply.
