What does the coding of a nozzle mean?

Nozzle coding is the information displayed on a nozzle. It includes the characteristics of the nozzle in the form of numbers and letters, namely the nozzle type, the vertex angle, the release value, the brand, the material and the colour coding. Our expert will gladly explain the nozzle coding to you.

Nozzle coding

Types of nozzles

There are various types of nozzle available, each with different characteristics. The type of cap is indicated on the nozzle with letters.
Flat spray nozzlesWhirl nozzlesImpact nozzles
... = standard
XR = large pressure range
DG = anti drift
AI - air injection (venturi)
UB = side nozzle
OC = eccentric nozzle FL = full conical nozzle
FL = full conical nozzleTXA = hollow conical nozzle
TXB = hollow conical nozzle
TF = precision impact nozzle

Brand

There are various brands of nozzles available. Royal Brinkman supplies the range of nozzles manufactured by Teejet.

Vertex angle

The vertex angle is the angle at which the spraying fluid leaves the nozzle. The vertex angle is particularly important when using a spray boom.

Colour code

The colour code indicates the quantity of fluid ejected per minute at a pressure of 2 bar.

ISO colour code Pressure filter (mesh) Litres per minute at 2 bar Litres per hectare at 6 km/h and at 2 bar 
01 (orange)1000.3365
015 (green)1000.4998
02 (yellow)500.65131 
025 (purple)500.98164
03 (blue)500.98196
04 (red)501.31261
05 (brown)501.63327
06 (grey)501.96392 
08 (white)502.61523 

Types of nozzles

Material

Nozzles are available in three types of material. The material from which the nozzle is made is indicated by a letter depicted on it.
  • K: ceramics. This material is very hardwearing.
  • P: plastic. Although cheaper, this material is also less hardwearing than ceramics.
  • S: stainless steel. This material is extremely hardwearing and less sensitive to damage than ceramics.

Release

The number used to indicate the release of spraying fluid is indicated in gallons per minute at a pressure of 3 bars.
