Rain Bird® R-VAN Adjustable Rotary Nozzles provide water efficiency and design flexibility. R-VAN Adjustable Rotary Nozzles feature rotating stream technology which uniformly delivers water at a low precipitation rate, significantly reducing runoff and erosion. They adjust from 45° – 270°. Full Circle Nozzles are a fixed 360° spray.

Retrofitting standard spray nozzles with R-VAN Adjustable Rotary Nozzles can reduce flow by up to 60% and improve water efficiency by up to 30%. Nozzle spray pattern and distance are easily adjusted by hand with no tools required. Thick wind-resistant streams ensure efficient performance in adverse real world conditions. Large water droplets cut through the wind so water stays in the target zone without misting or fogging. An exclusive manual flush feature keeps nozzles clear of dirt and debris even in extreme conditions.

Adjustable arc from 45° – 270°.
Adjust arc and radius without tools
Full circle nozzles are a fixed 360° and is not adjustable.
Color coded for easy identification of R-VAN model
Low precipitation rate reduces run-off and erosion
Maintains efficient performance at high operating pressures without misting or fogging
Compatible with all models of Rain Bird spray bodies in addition to a wide variety of risers and adapters
Matched precipitation rates across radius and arcs simplify the design process
Coverage up to 24’ but when paired with Rain Bird 5000 Series Rotor matched precipitation rate (MPR) nozzles, irrigation designs from 13’ to 35’ (4,0m to 10,7m) can be easily handled

Low Flow Rotator Nozzles FAQs

What’s the best type of sprinkler for my garden?

There’s no best type of sprinkler, just better sprinklers for different applications. Gear Drives are better for large areas, over 5m. Pop-Ups are ideal for 1.5-5m & Micro sprays are excellent for anything under that.

What type of nozzles should I use?

The type of nozzle all depends on how far you need to spray, each nozzle is specified by the radius it sprays & the spray arc it provides (0-360 degrees). Aim to spray to the base of the next closest sprinkler for even watering. For more information on planning, check out our Product Guides.

How many sprinklers can I have on a single irrigation zone?

Each sprinkler & nozzle will push out water at different rates, but the key factor is the flow rate of your water supply. Work that out with a simple timed bucket test. From there, you can work out how much water each sprinkler you’re looking at uses & work within your flow limit. For more information, check our Product Guides.

Should I flush my watering system before running it?

As you install a system, it’s almost inevitable that small fragments of dirt will get into the pipe, for this reason you should always flush out the system before running it the first time. This can be done by leaving an open end at the farthest point of each irrigation zone & operating the zone for 15 or so seconds to flush it out. Then plug it up & you’re good to go! This can also be said for any other times dirt may have gotten into the system (eg: further irrigation repairs or a mains water supply fault).

Can I have drip tube & sprinklers on the same irrigation zone?

We definitely don’t recommend it. Typically, drip tube will deliver the water at a far slower rate that sprays. Because of this, if you were to have both on the same zone, the areas with drip would be left far drier than the areas with sprinkler coverage. If you do want to water some areas with drip & some with sprinklers, it can be done, but each will just need to be run on their own separate irrigation zones.

How far apart should I position my sprinklers from each other?

Firstly, each sprinkler &/or nozzle has a specified spray radius. Secondly, sprinklers are typically designed to deliver more water at their base & progressively less the further away you get. For this reason, you want to position sprinklers so they spray to hit the base of the next sprinkler. Of course this isn’t possible all the time so in those cases, aim to spray at least 80% of the way. By doing this you will guarantee even water across your lawn or garden.

Do I need a filter on my irrigation system?

Even on a typical domestic system running on mains water a filter is still a good idea. In the event of a water main fault where rubbish does find it’s way down the line, a filter will protect the system from blockage and or failure. On systems operating off recycled water, like from a tank, a screen filter is mandatory. Debris like silt & dirt from recycled water is the most common cause of blockages of failures in irrigation systems.
