K-Rain 4000 Series 4 Outlet Indexing Valve (4 Cams) 1-1/4 in. Slip | 4404

Product Overview

System failures due to malfunctioning indexing valves often lead to catastrophic turf damage and dry spots during the peak of the summer heat. When an indexing valve fails to cycle correctly, your clients face total system shutdowns and potential code violations regarding water runoff. With peak season demand increasing and supply chain lead times remaining unpredictable, waiting until a valve fails to order a replacement is a risk to your project deadlines. Securing the K-Rain 4000 Series now ensures your crews can address repairs immediately or complete new installs without the frustration of back-ordered components, keeping your clients satisfied and your schedule intact.

The K-Rain 4000 Series indexing valve offers a distinct technical advantage over complex manifold systems by providing a high flow, low maintenance alternative to multiple electric solenoids. By utilizing a single station controller or even a simple pump start relay, you significantly reduce the amount of wire and labor required for a multi-zone installation. This 4-outlet model simplifies the hydraulic layout of your systems, lowering long-term maintenance costs because there are fewer electrical components to troubleshoot in the field. Maintaining a stock of these durable units gives your business a competitive edge by allowing for cleaner installations and faster service calls.

• Simple internal design features a single moving part which reduces the likelihood of mechanical failure compared to traditional valve banks.
• The slip connection design allows for fast solvent welding with standard PVC primers and glues in the field.
• Compatible with both city water and well water pump systems for maximum flexibility across different job sites.
• Allows for easy manual rotation of the cam assembly to test individual zones without needing to cycle the entire controller.

Common Applications

• Residential lawn and garden systems
• Agricultural and crop irrigation
• Municipal parks and public spaces
• Greenhouse and nursery operations
• Sports turf and golf course maintenance
• Commercial landscape irrigation

Installation Notes

Ensure that the valve is installed in a level, upright position to allow the internal cam assembly to drop and rotate freely via gravity. Installers should use a high quality PVC solvent cement on the 1-1/4 inch slip connections and allow for adequate cure time before pressurizing the system. It is highly recommended to install a filter upstream of the valve to prevent sand or debris from interfering with the rotation of the internal disk. Always follow local plumbing codes regarding backflow prevention when connecting to a potable water supply.
