The operating pressure of these nozzles is user adjustable. Pressure adjustment is performed by twisting a knob on the front of the
nozzle to the desired pressure setting. The following figures show typical flow performance for each model when adjusted to marked
pressure settings. The automatic pressure control will maintain the set pressure anywhere within the flow ranges shown on the graphs,
which vary according to pressure setting.
