Multi-zone distribution for greywater irrigation

The GreyFlow™ 6-way rotor valve is used to distribute water from a GreyFlow™ or G-Flow system into separate irrigation zones.

Simple, reliable and easy to install, the rotor valve can improve system performance by splitting flows into different zones and increasing operating pressure to each section.

Sequential zone control without external power

• One valve operates evenly and sequentially across 2, 3 or 6 zones.
• Hydraulic operation means no external power is required.
• Flow-activated design can operate from a gravity-fed tank with less than one metre of head pressure.
• Suitable for a range of watering systems, including sprinklers, drip, garden taps, greywater systems and wastewater systems.
• Improves system performance by splitting flows and increasing operating pressure to individual zones.
• Simple, reliable and easy to operate and install.
• Includes a 2-year manufacturer’s warranty.
