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

Our products are grouped into these primary product types:
- Nozzle - Body _(a nozzle body without a spray tip)_
- Tip _(a spray tip without a nozzle body)_
- Assembly _(a complete nozzle assembly including both a nozzle body and a spray tip)_

Product Type

Many hydraulic spray nozzles include a numeric capacity size in the part number. Capacity size is often related to the flow rate of the nozzle at the rated spray pressure for that nozzle. For example, the capacity size for a 1/4HH10 FullJet® nozzle is “10”, which reflects a 1.0 gpm flow rate at 10 psi.

Capacity Size

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.

Inlet Connection Size

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.

Specific Gravity

Model

Different nozzle types are _**“rated”**_ at various pressures, depending on the function of the nozzle and the pressure at which a spray pattern is fully formed. The angle of the spray pattern as it emerges from the nozzle, when spraying at the rated pressure orifice, can serve as a reference point for comparing different nozzles.

Spray Angle at Rated Pressure

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.

* Staked-in vane will not fall out during operation
* Hex body allows standard sockets for installation/removal
* Full cone spray pattern with uniform distribution
* Low profile design

 Flow:
* The liquid enters the nozzle and proceeds through the vane.
* The vane causes the liquid to swirl.
* The design of the nozzle ensures the liquid continues to swirl as it enters the orifice.
* The liquid breaks up as it exits the nozzle orifice forming a well defined cone pattern.
* The drops are uniform in size and distributed equally throughout the spray pattern.
