Spray nozzles are manufactured from a wide variety of materials that have been determined to meet the usual requirements of the applications most commonly associated with that type of nozzle. Standard materials include brass, steel, various stainless steels, hardened stainless steels, many plastics and various carbides. Spray nozzles can also be supplied in other materials upon special request. Materials of construction affect nozzle wear life and resistance to corrosion and abrasion.

Materials

The volume of liquid passing through a nozzle (also called the nozzle’s capacity) is typically measured in gallons per minute or liters per minute. Flow rate is affected by liquid pressure and other factors, including the specific gravity and viscosity of the liquid being sprayed.

Liquid Flow Rate

Standard hydraulic nozzles range in connection size from 1/8” threaded nozzles up to those with 12” flange connections. Larger connection sizes typically have larger flow rates but a wide variety of configurations are available to meet your application needs.

Specific gravity is the ratio of the density of a fluid compared to the density of water. It must be considered to properly calculate flow rate. 

 **Alternatively**, if you don't know the specific gravity you may select the **Liquid Type** from a list of commonly-sprayed liquids and temperatures.

### Liquid Type

 The type of liquid sprayed and its temperature affects the specific gravity of the liquid and in turn affects the flow rate. The default liquid is water, with a specific gravity of 1.

We offer the _**“brand”**_ filter as a convenience because many Spraying Systems Co. nozzle brand names are recognized by customers around the world, such as VeeJet® flat spray nozzles and FullJet® full cone nozzles. Most of our nozzle brands are registered trademarks in the United States and in other countries around the world.

The angle of the spray pattern as it emerges from the nozzle orifice, measured in degrees. Narrower spray angles provide less coverage of the sprayed surface. Wider spray angles provide greater coverage of the sprayed surface. Solid stream nozzles have a 0° spray angle.

WhirlJet® Hollow Cone Nozzles - Offset Style

In-line hollow cone nozzles have a hole on the inlet side of the nozzle through which liquid passes into a whirlchamber which spins the liquid at high speed. The rotation causes the liquid to exit the orifice in a hollow cone pattern. The direction of the spray is the same as the liquid inlet.

In-Line Hollow Cone Nozzles

* Hollow cone spray pattern
* In-line versions ideal for dust control in mining operations 
* BD versions have a lower profile projection for installation in a tee or pipe header 
* In-line BDM features recessed orifice area to protect from damage; self-locking cap to prevent loss due to vibration; fiberglass-reinforced nylon inlet body
* BA offset style ideal for installations with physical space limitations
* Spray angles: Standard – 43° to 94°, Wide – 102° to 125°
* Deflected spray versions available with 120°, 150° and 180°included angle of spray at 10 psi (0.7 bar)
* Uniform spray distribution from .11 to 38 gpm (.41 to 145 lpm)
* Operating pressures up to 500 psi (35 bar)
