Full Cone Spray Nozzles are one of the most versatile types and
are used in countless appplications in all industries. They are
available in many variations of full cone spray patterns, from
narrow - high impact 15° round spray used for tough cleaning
applications, to a light impact, extra wide angle rectangular
spray used for rinsing delicate products such as soft fruit. Flow
rates range form tenths of gallons per minute, to deluge sprays
of thousands of gallons per minute, and everything in between.

 Standard
Full Cone Spray Nozzles
Standard Type GJB and GGJB are three-piece
spray nozzles. The cap and internal helical vane can be
removed for cleaning or replacement without disturbing the
pipe connection of the nozzle body. As the cap and vane
are the main wear parts, this makes maintenance easy. The
spray pattern is circular with spray angles in the 50 to
90 degree range. Pipe connections sizes are from 1/8" to
1/2" in male and female NPT and ANSI flanged connections
for the larger pipe sizes.

 Maximum
Free Passage Full Cone Spray Nozzles
Maximum Free Passage full cone spray nozzles are designed
for maximum clog resistance. The modified internal vanes
which form the full cone pattern, have the largest free
passage size of any of the full cone spray nozzles. They
can handle solids of 2 to 3 times the diameter of those
that will pass through standard full cone spray nozzles
of the same capacity. This enables them to be used
reliably with liquids containing solid particulate. Care
has been taken to ensure that the more open vane design
does not compromise the spray pattern quality. They produce
a circular full cone pattern with standard or wide spray
and a choice of spray angles fro 30° to 120°.

 Spiral
Design Full Cone Spray Nozzles
Spiral full cone spray nozzles are designed to provide
a full cone spray pattern without the restriction of an
internal vane. By positioning the "vane" outside the nozzle,
the maximum free passage - or the ability to pass solids
- can be increased. This feature makes the spiral full cone
nozzles especially well suited for applications where solids
may be present in the liquid being sprayed. For example,
recirculated wash water, or some chemical scrubbing applications
using slurries. The clog resistance provides performance
reliability in critical applications such as fire suppression
and prevention, where nozzles are inactive most of the time,
but when activated the must operate without fail, even with
dirty water.
