NOZZLE IDENTIFICATION CODESPNR CODING SYSTEM

As any other industrial product, spray nozzles need to be precisely identified by means of a code in order to avoidmistakes.PNR coding system has been designed with the following requirements in mind:- Codes must be easily processed by a computer, in ascending order. - Codes must describe completely the product without any need for additional description. - Codes must show to the user the basic specifications of the nozzle in order to ease the search in the catalogue. We have therefore determined our coding system described as follows:

AA U 2 305 B31 X Y

Nozzle tables report on a blue background the nominal flow value, measured at 3,0 bar. Flow values at different pressures have beencalculated. Thread type or other connectionSpecial featuresNozzle material code (see below)The three digits give the nozzle capacity in lpm at 3 baraccording to rank valueRank of flow value, see table belowNozzle spray angle, see table belowNozzle type, as described in the catalogue pages, shownin ascending order These codes serve as an indication only.Based on different types of nozzles, their significancecan occasionally be different.
