Rain Bird HE-VAN Series High-Efficiency Variable Arc Nozzles | 8' to 15' Radii

Product Details

The Rain Bird HE-VAN (High-Efficiency Variable Arc Nozzle) series represents a significant leap forward in adjustable spray technology. Designed to tackle the inefficiencies of traditional variable arc nozzles, the HE-VAN delivers superior distribution uniformity and wind-resistant droplets. With patent-pending Flow Control Technology, these nozzles provide exceptional close-in watering to eliminate dry spots around the spray head. Their high efficiency allows you to shorten zone run times by up to 35%, conserving water while maintaining a lush, healthy landscape. Fully adjustable from 0° to 360°, they are the perfect solution for odd-shaped areas and standard lawns alike.

Key Features:

• Superior Uniformity: Achieves a DULQ (Distribution Uniformity) of 70%, a 40% improvement over standard variable arc nozzles.
• Wind-Resistant Streams: Produces larger water droplets and a low-trajectory spray to minimize misting and airborne evaporation.
• Tactile Click Adjustment: Features a physical "click" when adjusting the arc, ensuring the setting stays locked and doesn't drift over time.
• Matched Precipitation: Can be installed on the same zone as Rain Bird MPR and U-Series nozzles without over- or under-watering specific areas.
• ExactEdge™ Technology: Provides a clean, consistent edge at the arc boundaries for precise watering that stays off sidewalks and driveways.

  • HE-VAN-15: 12 to 15 feet (Black)
• Warranty: 3-Year Trade Warranty

Installation & Maintenance Tips:

• No Tools Required: Simply twist the center collar to increase or decrease the arc setting. Use the stainless steel top screw to reduce the radius by up to 25%.
• Filter Screens: Always use the included color-coded filter screens to prevent debris from clogging the high-efficiency ports.
• Pressure Regulation: For systems with pressure exceeding 30 PSI, use Rain Bird 1800-PRS spray bodies to maintain optimal nozzle performance and prevent misting.
• Left Edge Alignment: Rotate the entire spray head riser to align the fixed left edge before adjusting the right-side arc.

Common Uses/Applications:

• Irregular Landscapes: Ideal for curved flower beds, traffic islands, and corner lots where fixed-pattern nozzles don't fit.
• Residential Lawns: Provides professional-grade efficiency that significantly lowers monthly water bills.
• Windy Areas: The heavy droplets make these the best choice for coastal or open-plain regions where wind drift is a concern.
• Water-Restricted Zones: Helps meet tight watering windows by delivering more water in less time with higher precision.

Common Questions:

Q: Can I replace my old standard VAN nozzles with these?

A: Yes. HE-VAN nozzles fit all Rain Bird spray heads and shrub adapters, and are compatible with any brand of male-threaded riser.

Q: Will these work at high pressure?

A: While they will operate, pressure above 30 PSI can cause "misting." Using a pressure-regulating (PRS) spray head is recommended for maximum efficiency.

Q: Do I need a special tool to adjust them?

A: No. The arc is adjusted by hand using the textured center collar. A standard flat-head screwdriver is only needed if you wish to reduce the throw radius.

Rain Bird HE-VAN nozzles are the smartest way to upgrade your existing irrigation system for better coverage, healthier plants, and lower water costs.
