Double-Down Turret Outlet

Why use the double-down turret outlet?

With high flow applications, often the sheer volume sprayed out of a single spray tip becomes too coarse to be effective for coverage-dependent spray applications.

With splitting the volume, you can make more effective and meaningful droplets for your application, to improve coverage and still manage drift reduction. The double-down outlet provides perks over the multi-angle spray tips or spray adapters, which still split up spray volume, but multi-angle spraying can increase the spray distance and penetration dramatically, resulting in less effective spray on many crop applications.

How can I use it today?

STEP 1: Retro-Fit on CRII Turret Bodies

Simply (& Carefully) remove diaphragm check valve (or solenoid). 

STEP 1 [For Side Take-Off Turrets]

If you have a turret that houses the check valve or solenoid off the side of the turret, unscrew the two (phillips) screws holding the faceplate with the WILGER logo on it.

STEP 2: Remove Turret Hub Lock Ring

Gently pry turret hub lock ring off from remaining turret, and slide off one of the turret’s existing outlets. Ensure to keep area clean as possible, and ensure precautions are taken with contaminated nozzle bodies.

STEP 3: Replace Outlet with Double-Down

With the turret  with an open outlet slot, replace with a new double-down outlet (#41502-13) and outlet o-ring seal (#20455-07), and slide into the turret outlet slot. Ensure the o-ring is seated properly, and not pinched.

Simply replace turret hub lock ring and screw on check valve/solenoid.

For side take-off turrets, replace & carefully screw in cover plate.

How do I select spray tips when spraying two tips at once?

[OPTIONAL] Use Tip Wizard to find a nozzle size that would apply the full rate with a single tip.

For example, if a tip search (15 US GPA; 12 MPH; 20″ spacing) led you to using an SR110-06 for the full rate out of a single spray tip.

How to Use Tip Wizard for Standard Sprayers, such as speed + pressure sprayers, auto-rate controlled sprayers, etc.

STEP 1: Split the Spray Volume (15 US GPA) into two flow rates (or tip sizes).

For our example of a 15 US GPA application, which we know could be applied with an -06 size tip, we could:

  1. Split it evenly to two -03 tip sizes (as they will add to the same cumulative volume of an -06
  2. Split it into a ratio of the -06 size, typically trying to keep the tip sizes close together. (e.g. opt for a ‘-04’ + ‘-02’ split, than an ‘-05’ and ‘-01’ split)
Since each application is different, it is best to find the spray tip that suits your speed, coverage and drift control requirements, instead of picking a tip based on the series alone. Tip Wizard is the recommended tool to make picking spray tips easy.

Considerations: Pressure

Keep in mind when selecting spray tips between the two nozzles, the pressure will be shared across the two tips, so when making a tip selection, both tips will be spraying at X pressure, so the droplet size/driftable fines/etc would always be based on that common pressure.

Considerations: PWM-Systems

For PWM system users, there will be greater flexibility with the options for spray tips used, but consider the following:

  1. The pressure is still shared between the two tips, so pick your tips accordingly.
  2. Some PWM systems have inherent max flow capacities before significant pressure drop. Some of the PWM solenoids are able to maintain up to 20 US GPA while traveling 15 MPH; or inversely, 15 US GPA while travelling 20 MPH.
    Many of the PWM system manufacturers have high-flow solenoids or effective options to apply more than a nominal 20 US GPA @ 15 MPH, but ensure to ask your system manufacturer what the max flow could be.
