High Efficiency Variable Arc Nozzle (HE-VAN) Series
Use 35% Less Water
Rain Bird HE-VAN nozzles offer even coverage throughout the spray pattern, delivering a healthy, beautiful landscape. Gentle close‑in watering eliminates dry spots around the spray head. HE-VAN nozzles also generate large wind-resistant water droplets that prevent misting and airborne evaporation, so the right amount of water is delivered to the right place.
The high efficiency of the HE-VAN nozzle allows you to shorten your sprinkler run times by up to 35%, saving you water and money. Even coverage makes them the perfect choice for homeowners looking to conserve water while maintaining a healthy beautiful landscape.
Now available in popular 8', 10', 12’, and 15’ radii, HE-VAN nozzles also offer matched precipitation with Rain Bird MPR and Dual Spray Series nozzles.
Perfectly Paired for Pressure Regulation
When used with 1800 PRS Sprays, Rain Bird R-VAN Rotary Nozzles provide ultimate efficiency at 30 psi.

Efficiency Ratings
- Rain Bird HE-VAN Nozzles deliver an average DULQ of 70%, more than a 40% improvement over typical variable arc spray nozzles.
- Rain Bird HE-VAN Nozzles deliver a SC less than or equal to 1.6, which is 35% lower than the typical variable arc spray nozzle.
Distribution Uniformity (DULQ): DU in irrigation is a measure of how uniformly water is applied to the area being watered. DULQ is calculated by taking the volume in the lowest quarter of catch can measurements and dividing it by the average volume of all catch can measurements. Scheduling Coefficient (SC): SC is a measure of how long a zone must be run in order to provide adequate water to the driest spot.
Operating Range
- Spacing: 6 to 15 feet (1.8 to 4.6 m)¹
- Pressure: 15 to 30 psi (1.0 to 2.1 bar)
- Optimum pressure: 30 psi (2.1 bar)²
¹ These ranges are based on proper pressure at nozzle.
² Rain Bird recommends using 1800 PRS Spray Bodies to maintain optimum nozzle performance in higher pressure situations.
