Cone Spray
Nozzles whose spray is emitted in a conical shape and a round cross section. Cone sprays have less impact than flat sprays and are therefore better suited for rinsing and wetting.

Solid Cone Spray Nozzles
Cone Spray Nozzles in which the cross section distribution shows little or no droplets in the center and with most of the spray concentrated at the outer edge.

Hollow Cone Spray Nozzles
Cone Spray Nozzles in which the cross section distribution shows little or no droplets in the center and with most of the spray concentrated at the outer edge.

Flat Sprays
Also known as fan sprays, these Nozzles produce either a tiat or elliptical sheet of water. They are best suited for washing operations where high Impact Is desirable. The spray normally breaks into individual droplets a few Inches from the orifice.

Atomizing Nozzles
Produce a highly atomized hollow cone spray. Their light mist ranges from a fog that hangs in the air to slightly larger droplets that fall by gravity. They are most typically used for humldification and very light wetting.

Jet Nozzles
Produce a straight unbroken stream of water nominally referred to as a 0° spray angle. Depending on the piping set up, onfice size and water pressure, the stream may remain unbroken from a few Inches up to 3 or 4 feet. For blasting and light cutting applications.

Spray Angle
The included angle of the spray emitted from the Nozzle orifice. This excludes the light “fuzz” at the edge of some sprays, particularly those of low flow rates. Higher operating pressures usually tend to compress the spray, thereby resulting in a nar rower spray angle. Liquids with surface tensions lower than water will produce wider spray angles than those of water. See chart on page 16 for coverage data.

Nozzle opening
The aperture through which the liquid exits the Nozzle. It measures the liquid and its contours produce the various spray angles. It Is normally round but can be elliptical In the case of flat spray Nozzles. On most Nozzles the orifice is a highly polished surface. It should never be probed with any metal object. A wooden toothpick is the best tool for cleaning or unclogglng an orifice.

Pressure
The force with which the liquid einfliet in the nozzle, in PSI (pounds per square foot: 1PSI = 0.6848 N / cm). Generally produces more favorable to operate at pressures smaller droplets, tighter and denser spray angle Saying Pictures. Conversely, low pressure leads to larger droplets, slightly wider angle and a less dense distribution.

Minimum operating pressure
lowest possible The pressure at which the kinetic energy of the liquid is sufficient to produce a fully developed jet. Data flow in the nozzle tables indicate that value for water. He can be HHer or lower if other fluids are used as water because it depends on the specific weight and Viscosity the liquid.

NPT
National Pipe Thread (American standard pipe thread). This is a tapering thread that participates in the installation of self-tightening. A thread seal as “pipe dope or Teflon tape is needed in order to seal properly.

Spray Atomization
A Spray Nozzle breaks up a flow of liquid into many small droplets. The efficiency, or results, of the spray process greatly depend on droplet size and distribution. Droplet size may range from a few to thousands of microns in diameter depending upon the liquid being sprayed, the pressure and Nozzle design. Nozzles do not generate droplets of equal size. There is usually a broad spectrum of droplet sizes within a spray. Larger droplets occur as nozzle capacity increases. Coarse atomization is often associated with narrow angles or straight streams. For a given nozzle, fineness of atomization may be improved by increasing pressure.

The two important liquid parameters affecting atomization are viscosity and surface tension. Compared with viscosity, surface tension has a relatively minor affect.

Spray Velocity
The velocity of the spray leaving a Nozzle orifice depends upon the liquid pressure. The velocity is also determined by the design characteristics of the specific Nozzle. Solid stream and flat spray Nozzles will have, under equal conditions, higher velocities than wide angle, round cone Nozzles.

GPH
Gallons per hour (gallons per hour: 1 gallon = 3.7853 l). This size unit is always based on water flow. See the table for a given nozzle to determine the pressure of her flow.

GPM
Gallons per minute (gallons per minute). The unit size for nozzles with a larger flow rate, based on water flow. See the table for a given nozzle to determine the pressure of her flow.

CFM
Cubic feet per minute (cubic foot per minute). A measure of the volume of gas (usually air) describes the spray. Spray nozzle operated in an air nozzle

Note
Some of our jets, which are listed as Full cone spray nozzles can be brought also to create a Hollow cone beam, although this is not mentioned specifically. If a particular nozzle configuration meets your needs, but has the wrong reason, beam pattern, please let us know. Bullet We look forward, if we are going to help you meet your potential.
