These are primarily designed to spray liquid tar, bitumen emulsion, or water onto the road or footpath. All the nozzles are made from 30mm solid brass bar and have a 1/2 inch British Standard Pipe Thread (tapered) for assembly onto a spray bar.
Uses
Copley Spray Nozzles® are primarily designed to spray liquid tar, bitumen emulsion, or water on to the road or footpath.
They are also used to spray water onto earth work for consolidating road foundations, and to spray water onto concrete during the curing period.
All the nozzles are made from 30mm solid brass bar and have a 1/2 inch British Standard Pipe Thread (tapered) for assembly on to a spray bar.
Types of Nozzles
There are two distinct types of nozzles:
1. INTERMEDIATE (also known as standard nozzles), the general features of which are shown in Fig. B.
2. END NOZZLES shown in Fig. C. These end nozzles are only used on the two outer ends of a spray bar.
The nozzles are made with various sizes of orifice to give different rates of discharge. For each size of intermediate nozzle, there is a corresponding END NOZZLE marked thus.
The discharge rate of the end nozzles is approximately double of that of the corresponding intermediate nozzles.
ORIFICE SIZES
The purpose of having a range of orifice sizes is to facilitate the spraying of heavy or light applications of liquid to the surface without the necessity of having the spraying vehicle travelling at too slow or too high a speed. This also avoids the necessity of getting too far away from the designed rate of discharge of each nozzle.
| Nozzle (old) | Orifice Width | Discharge Rate |
|---|---|---|
| B36 (B8) | 4.44mm | 36.36lt/min |
| B27 (B6) | 3.81mm | 27.27lt/min |
| A18 (AN18) | 3.37mm | 18.18lt/min |
| A14 (A3) | 2.92mm | 13.63lt/min |
| S9 (S2) | 2.31mm | 9.09lt/min |
| S4.5 (S1) | 1.56mm | 4.54lt/min |
For each size of intermediate nozzle, there is a corresponding end nozzle marked as: EB36, EB27, EA18, EA18W, EA14, ES9, ES4.5
The discharge rate of end nozzles is approximately double that of the same intermediate nozzles.
We are happy to work collaboratively with our customers on special design nozzles for specific requirements.
