Choosing the perfect nozzle for your sprayer can be a daunting task. Achieving adequate spray coverage is critical to the effectiveness of contact herbicides. When it comes to pesticide applications nozzle selection is one of the most crucial decisions to make.
Each nozzle type has explicit qualities and capacities that are intended for use under certain application conditions. The most commonly used nozzles are flat-fan, even flat-fan, and cone nozzle. As there is a number of different nozzles out there, so you need to consult with an expert to identify the right nozzle for you.
Let’s check out various types of nozzles, so you can decide the perfect nozzle for you.
Regular flat-fan nozzle
Starting with the regular nozzle, which is an 80-degree flat fan. This nozzle is designed to work well between about 20 and 60 psi. When you go to lower pressures, the pattern does collapse, and the spray gets coarser. When you go to the higher pressures the pattern forms nicely, but it can become very drift-prone which is a problem with this nozzle.
These nozzles are utilized for most communicate showering of herbicides and for specific bug sprays when foliar entrance and inclusion aren’t required. These nozzles produce a level of oval shower design with decreased edges. They are accessible in splash fan angles of 65, 80, and 110 degrees and are generally separated 20 inches apart on the blast at a height of 15-24 inches.
The ordinary prescribed working weight for the regular flat-fan nozzle is 20 to 30 psi. At these weights, this nozzle type will create medium to coarse drops that are not as vulnerable to drift as the better drops delivered at weights of 40 psi or greater. At these higher weights, the probability of drift increases fundamentally so suitable safeguards must be taken to limit its effects.

Extended range flat-fan nozzle
The extended range flat-fan nozzle fluctuates the droplet size and stream rate by rotating pressures. It holds its pattern at a low weight, guaranteeing uniform inclusion along with the blast. Expanded range level fan nozzles are accessible in both 80 and 110-degree fan edges.
For soil applications, the prescribed weight territory is from 10 to 30 psi. Littler drops are created at pressures from 30 to 60 psi, improving the probability of drift. High weights ought to be utilized uniquely to apply foliar pesticides that must enter into the plant canopy or that require the most extreme inclusion. Spray drift is a significant worry at pressures of more than 40 psi.
Drift reduction pre-orifice nozzle
These nozzles produce a standard level fan design while adequately bringing down the exit pressure at the nozzle. The lowered exit pressure makes a bigger droplet range with less driftable fines, limiting the off-target development of the spray design.
Currently, there are two styles of drift reduction flat-spray nozzles available. One is the RF Raindrops flat spray nozzle which is accessible with a 105 to 115-degree fan angle, and the other one is Drift Guard flat spray nozzle which is accessible in both 80 and 110-degree fan angles.
With a bigger droplet size, these nozzles can substitute ordinary flat fan 80 and 110-degree tips in broadcast applications where spray drift is an issue. The suggested weight for this nozzle is 30 to 60 psi. An option to the pre-orifice nozzle is utilizing a bigger expanded range level fan nozzle worked at a lower pressure.
Turbo flat-fan nozzle
These nozzles are designed to deliver less turbulence within the nozzle body. So, for this reason, it causes less wear and longer life. Moreover, these nozzles deliver large droplets that won’t drift and are available in a 110-degree fan angle.
When drift isn’t a major concern and plant foliage penetration is necessary for effective insect or disease control that is when cone nozzles are mainly used. At weights of 40 to 80 psi, these nozzles deliver little droplets that promptly enter plant canopies and spread the underside of the leaves more successfully than some other nozzle type.
However, as a result of the little droplets delivered and high working weights, these nozzles produce designs that are truly helpless to drift. So, it should in this manner never be utilized with any compound for which drift can cause an issue. They are also exceptionally hard to arrange along with a blast for uniform circulation and are subsequently not suggested for broadcasting herbicides.
The two normal styles of cone nozzles accessible are the solid cone and hollow cone. The solid cone nozzle delivers a cone-molded design with a uniform appropriation of chemicals all through the design. On the other hand, the hollow cone nozzles produce a cone-molded design with the spray gathered in a ring around the external edge of the design.

Different kinds of nozzle bodies and tops, including color-coded versions, and numerous nozzle bodies are available. You’ll also get threads as well as quick-attaching adapters. Nozzle tips are exchangeable in the top and are available in a wide range of materials, including solidified hardened stainless steel, tempered steel, metal, ceramic, and different sorts of plastic.
Solidified hardened stainless steel and ceramic are the most wear-safe materials but at the same time are the most costly. Stainless steel tips, with destructive or abrasive materials, have amazing wear-resistant. Plastic tips are resistant to consumption and are ending up being affordable for applying pesticides.
Metal tips have been normal yet wear quickly when used to apply abrasive materials, for example, wettable powders and are consumed by some fluid fertilizers. Metal tips are economical for its limited use, yet different sorts should be considered for progressively broad use.

Though the nozzles are generally the least costly parts on a sprayer, however, they play a crucial role in the final outcome. Pesticides work well if the rates on labels are achieved during application and this can be only possible if the right nozzle types along with the proper size are on the sprayer.
It’s best to understand the process the nozzle manufacturers use to get the values. So, we hope that our article will help you and should give you serious consideration when selecting the best nozzle for a spraying job.
