Rain Bird’s R-VAN rotary nozzles are hand-adjustable, eliminating the need for special tools. These nozzles offer a low precipitation rate that reduces run-off and erosion, making them a particularly wise choice for slopes and compacted soils. A high level of distribution uniformity, thick wind-resistant streams and larger water droplets ensure efficient performance, even in adverse conditions. R-VAN nozzles are compatible with all models of Rain Bird spray bodies and a wide variety of risers and adapters. Retrofitting standard spray nozzles with R-VAN Adjustable Rotary Nozzles can reduce flow rates by up to 60 percent and improve water efficiency by up to 30 percent.
