Spray Nozzle Characteristics
Hollow Cone Nozzle
The hollow cone nozzle spray pattern is essentially a circular ring of liquid. This pattern is generally formed by use of an inlet tangential to a whirlchamber, or by an internal grooved vane immediately upstream from the orifice. The whirling liquid results in a hollow cone configuration as it leaves the orifice.
Standard hollow cone nozzles feature a large and unobstructed flow passage, which minimizes or eliminates clogging.
The in-line style has a lower profile projection when installed in a tee or pipe header.
Spiral nozzles produce a hollow cone spray pattern with spray angles ranging from 50º to 180º.
Deflected-type spray nozzles feature a ring-shaped impact area. Angles of deflection available are 120º, 150º, and 180º.
Full Cone Nozzle
Full Cone nozzles have a spray pattern that is round, square, or oval. The spray pattern is completely filled with drops. Using an internal vane, which imparts controlled turbulance to the liquid prior to the orifice, forms this pattern.
Standard Full Cone nozzles produce a round cone-shaped spray pattern completely filled with drops. Using an internal vane forms the pattern.
High Impact Narrow Angle nozzles produce a cone-shaped spray in specific narrow spray angles.
Spiral nozzles have a round orifice and a corkscrew deflector surface, which produces a cone-shaped spray and allows maximum liquid throughput.
Maximum Free Passage nozzles provide the largest free passage of any spray nozzle of its type.
Square spray pattern nozzles produce a solid square or rectangular shaped spray. The Oval spray pattern nozzles produce a pattern width approximately half of its length.
Vaneless nozzles feature an unrestricted internal flow passage with no vane. The spray is projected from the nozzle is at an axis of 90º from the axis of the nozzle inlet.
Large Capacity Fixed Spray Angle nozzles feature a solid cone-shaped spray pattern with a round impact area and spray angles from 50 to 95 degrees.
Flat Spray Nozzle
A flat spray nozzle pattern distributes the liquid as a flat fan or sheet-type of spray. In the elliptical orifice design, the axis of the spray pattern is a continuation of the axis of the inlet pipe connection. In the deflector design, the deflection surface diverts the spray pattern away from the axis of the inlet pipe connection.
The tapering edges of the flat spray nozzles are useful in establishing overlapping patterns between adjacent sprays on a multiple nozzle header. The resulting distribution across the entire sprayed surface can therefore be uniform.
Standard flat spray nozzles feature an elliptical orifice design with the axis of the spray pattern as a continuation of the axis of the inlet pipe connection.
Deflector flat spray nozzles divert the spray pattern away from the axis of the inlet pipe connection.
Paint Nozzle / High Pressure Nozzle feature tungsten carbide orifice inserts for maximum erosion resistance. The flat spray pattern spray nozzles and spray tips produce a high impact with feathered edges for even coverage.
Wash Nozzle / High Pressure spray nozzles produce a uniform spray distribution of medium-sized drops. The orifices are precision-machined for accurate control of flow rates. These nozzles are designed for pressure wash applications and produce high impact sprays with adjustable spray angles from 0 to 80 degree flat sprays. The 24055 design will allow you to adjust for high pressure spray during washing and rinsing and low pressure for detergent siphoning.
Fine Spray Nozzle
These low capacity nozzles are available in Standard, Wide Angle and Narrow Angle, and produce very small drops. Air friction and currents affect the full cone and hollow cone spray patterns. Several feet from the nozzle, depending on pressure and nozzle capacity, the fine spray pattern disappears as the drops become suspended in air. They have uniform distribution, which often allows them to achieve misting performance.
Fine spray nozzles can be used for evaporative cooling, moistening and humidifying.
The Standard Fine Spray hydraulic atomizing spray nozzles use liquid pressure alone to produce very finely atomized drops. These spray tips have a core, body, and orifice insert and are applicable with the UniJet nozzle system. The spray tips produce very finely atomized drops in a hollow cone spray pattern of up to 90 degrees with uniform distribution, often achieving misting performance. Orifice inserts, cores, and strainers are easily removed for cleaning.
The Wide Angle Fine Spray hydraulic atomizing spray nozzles use liquid pressure alone to produce very finely atomized drops in a hollow cone spray pattern of up to 165 degrees.
The Narrow Angle Fine Spray hydraulic atomizing spray nozzles throw a fogging spray of small sized drops and produce a dense full cone pattern with large flow rates.
Solid Stream Nozzle
A solid stream spray pattern is a uniform stream of liquid. By using proper inlet chamber proportions and contours ahead of the orifice and/or by the addition of internal flow stabilizing vanes, these nozzles provide prolonged solid stream integrity and delay breakup and drop formation after leaving the nozzle orifice.
Solid Stream spray nozzles provide a high impact at lower pressures.
