Various spray patterns are available from different configurations of nozzle orifice and core.
Flat Pattern Straight Pattern Full-cone Pattern Hollow-cone Pattern
Use the following equation to calculate approximate values if it is necessary to determine flow rates for pressures other than that shown in the model number lists.
In general,the spray angle increases with increasing spray pressure. With some nozzle that have a core, such as a full-cone nozzle, however, the spray angle increases until the spray pressure reaches a certain value and decreases thereafter with the increase in spray pressure.
For increased widthwise uniformity in single-nozzle applications, it is desirable that the nozzle renders a uniform flow distribution with minimized shoulders. In some multiple-nozzle each nozzle renders a bell-shaped distribution.
