America's Best Sprinkler
THE PRN/LittleValve Combo
Combining Toro's® Precision Rotating Nozzle
& Valvette Systems' Patented In-Stem Flow Regulation (IFR)
= The Best Sprinkler Ever Made - Rotary Or Spray
The Ultimate in WATER SAVING SPRINKLERS
No other Sprinkler can Compare with the Benefits
of In-stem Flow Regulation
Especially when Paired with the PRN nozzle
Distance Range: 20 - 28 feet down to 18 inches
Arc range: 45° - 270°
The flexibility, efficiency and water savings of Toro's PRN when joined with Little Tuffys and LittleValve sprinkler parts is best described in the videos plus the pictures you'll see in the following 10 sub-pages
LittleValves make every nozzle and every sprinkler on the market work better but allow Toro's Precision Rotating Nozzle (PRN) to do things that no other nozzle can do. In fact, PRNs with LittleValve parts can replace every nozzle in your landscape except
for side, corner and center strips, (the nozzles used in long, narrow planter areas.)
Valvette Systems is the worldwide leader in water conservation sprinklers and parts.
The ultimate in high-efficiency irrigation. No other sprinkler is comparable.
In commercial installations, both PRNs and LittleValve parts are rebatable under
the Southern California Metropolitan Water District program.

When Combining the PRN with LittleValves, you have the most
ACCURATE, EFFICIENT and FLEXIBLE sprinkler available anywhere in the World.
Because you have a completely controllable radius Distance range
from 20 ft - 26 ft depending on pressure,
that can be brought all the way down to 18 inches - regardless of pressure.
You have an Arc range of 45° - 270°,
the Maximum Arc Range of all Rotating Nozzles on the Market today.
||See the 1½ ft radius PRN/LittleValve Combo video at the bottom of this page
|With the PRN/LittleValve combination, you can replace every spray nozzle [other than side strips and center strip nozzles] with proven water-saving, high-efficiency Rotating nozzles recognized by many municipalities and irrigation specifiers as the most efficient sprinkler nozzle available. Furthermore, the PRN/Little Valve combo eliminates as much as 95% - 98% of the water that usually ends up on adjacent streets and sidewalks - even in round planters and along meandering sidewalks. The videos and pictures on the next ten pages tell the whole story.
click here for the rotary comparison guide to see the vast differences
between the prn/littlevalve combo and the major competition
No other sprinkler - spray or rotary - handles curvy areas
like the PRN/LittleValve Combo.
No Sprinkler Anywhere in the World
has a Distance Range of 1½ feet up to 20 - 28 feet.
With the PRN/LittleValve combo sprinkler, you need to buy only the 2 models of PRN nozzles
- - Adjustable and Full Circle. That's it!
Now you can stop buying and keeping around all those different bags of nozzles that drive you nuts. Get rid of them!
You do not need any of the 5 - 6 different radius nozzles with all their many different arc patterns,
i.e. quarter circles, half circles, etc. etc.
You don't need the 5 - 7 different size adjustable nozzles offered by all the manufacturers,
and you don't need the other various arc and distance rotary nozzles available.
NOTE: For long, narrow areas, you can mix Toro's PSN side strips and left/right corner strips
with PRN nozzles because the flow rates are similar. [PSN = Precision Spray Nozzles]
When using side strip and corner strip nozzles at short distances, i.e. 3' - 6',
you can also mix Hunter's SS530, LCS515 and RCS515 into PRN systems.
See Nozzle Catalogue sub-page.
PRESENTING THE PRN AT A RADIUS OF 18 INCHES
Start the video to the right and watch the radius pattern with the longest PRN stream not exceeding 18 inches in its distance.
There is no standard Radius Nozzle on the Planet that can Maintain a distance of 18 inches except the PRN when connected to any Little Valve sprinkler part, a Little Tuffy pop-up sprinkler, or a Toro 570 pop-up with Precision Valve.
NOTE: The PRN's 18 inch distance was set on April 5, 2013. If this video is still up when you are watching it, that means the distance pattern has not changed since that date.
This 1 1/2 ft "distance project" was undertaken at the request of a certain customer in Northern California who has a long planter with an 18" width. Other nozzles were tried and did not perform satisfactorily. At this time, it appears that the PRN/LittleValve Combo is the answer.
We also are familiar with a project installed in the Summer of 2013 where the PRN radius distance has stayed at 14 inches. See Woodland Hills residence on sub-page 7 - about 1 minute into the video.
