Return nozzle
Fluidics nozzle W1 is a return nozzle
with integral, spring-loaded stop needle.
The flow is regulated by changing the
return pressure, while the supply
pressure is held constant. Before
commissioning, the nozzle size must be
compared with the output conveyed.
Replace the nozzle if necessary (see
nozzle selection diagram).
