FLAT JET SPRAY NOZZLES |
|
|
A flat jet spray nozzle produces a flat liquid
layer, also known as a flat fan or fan jet. A variety of spray angles are available to suit a wide spectrum of industrial applications.
- In-line flat jet nozzles
- Spoon jet or high impact nozzles

1.) In
Line Flat Jet (Pressure nozzle)
Here the liquid
enters the nozzle in line with its axis. The liquid is then fed to a pressure
chamber from where it is then forced through the nozzle orifice.
The flow value and spray angle is determined respectively by
the orifice cross section and the orifice profile.
1.b.) In Line Straight Jet (Pressure nozzle)
These are not strictly speaking flat jet spray nozzles. There is no spray angle
on these, but a straight jet
of liquid. A pencil jet, as they are also referred to, produces a sharp stable, stream with a powerful impact.

2.) Flat Jet or High
Impact Nozzle | Also known as a spoon jet
In this nozzle design the liquid is fed though the orifice and onto a smooth
curved surface
(which is also referred to as a spoon). This design also
produces a flat jet spray pattern.
The advantage of using this design is that it results in a
high impact jet of water, especially useful where cleaning is
involved.
