5.2 PATTERN CONTROL
The TFT Vortex nozzle allows the stream pattern to be infinitely varied from a straight stream to a uniformly dispersed Vortex pattern.
Typical stream results are shown in figures 5.2.1 and 5.2.2 below.

Full Vortex Pattern
The Shaper includes a tactile detent at the straight stream and full Vortex dispersed positions as a secure confirmation that the desired
setting has been achieved. As seen from the operating position behind the nozzle, twisting the stream shaper clockwise moves the
shaper to the straight stream position shown in figure 5.2.3. Twisting the shaper counterclockwise will result in an increasingly wider
pattern until reaching the full Vortex pattern shown in figure 5.2.4.

Pivoting the vanes has virtually no effect on the flow area or ability to pass debris up to 5/8”. As a result, discharge pressure and flow
rate remain constant regardless of stream pattern. The nozzle reaction is greatest when the shaper is in the straight stream position.
WARNING
The nozzle operator must be prepared for a change in reaction as the pattern is changed.
