Rain Bird R-Van18 Nozzles The Rain Bird R-VAN18 Adjustable Rotary Nozzle is a high-efficiency nozzle engineered to deliver water uniformly using rotating stream technology, which produces thick, wind-resistant streams and large water droplets. This advanced design ensures water stays in the target zone, significantly reducing runoff, erosion, and misting. Retrofitting your standard spray heads with the R-VAN18 can reduce flow by up to 60% and improve water efficiency by up to 30%. Designed for maximum convenience, the R-VAN18 allows you to adjust both the spray arc (from 45 to 270 degrees) and the radius (13-18 ft.) completely by hand—no tools required. Maintenance is just as simple, thanks to an exclusive pull-up-to-flush feature that instantly clears the nozzle of dirt and debris. Color-coded black for easy identification, this nozzle is a reliable solution for efficient performance, even in adverse, real-world conditions. Operating Range: Pressure Range: 30 to 55 psi (2.1 to 3.8 bar) Recommended Operating Pressure: 45 psi (3.1 bar) Spacing: 8’ to 24’ (2.4 to 7.3m) Adjustments: Arc and radius should be adjusted while water is running Quickly adjust arc and radius without tools Pull up flush feature clears the nozzle of dirt and debris Multiple, rotating streams uniformly distribute water throughout the radius range Low precipitation rate reduces run-off and erosion Matched precipitation rates across radius, arc and pattern types Maintains efficient performance at high operating pressures without misting or fogging Color-coded and laser-marked for easy identification of R-VAN model Compatible with all models of Rain Bird spray bodies, risers and adapters
