Copley Nozzles

Copley Bitumen Nozzles have been primarily designed to spray liquid tar, bitumen emulsion, or water on to the road or footpath.
The nozzles are manufactured with various orifice sizes to give different rates of discharge.

There are 2 distinct types of nozzles:-
1. Intermediate Nozzles – used along the spray bar.
Sizes available are:- S1, S2, A3, A4, B6, B8
2. End Nozzles – only used on the two outer ends of the spray bar. The discharge rates of end nozzles are approximately double that of the corresponding intermediate nozzle.Sizes available are:- ES1, ES2, EA3, EA4, EB6

The maximum uniformity of distribution of the liquid can only be achieved when the nozzles are assembled on the spray bar at:-

1. Correct spacing
2. Correct alignment of fan
3. Correct height above pavement
4. Correct volume of liquid per minute per nozzle.
All nozzles are manufactured from 7/8” square brass and have a 1/2” BSPT thread.
Cobra Head Screen Washing Nozzles

Cobra Head Nozzles are manufactured from tough, corrosion and abrasion resistant polyurethane. While the nozzles were developed specifically for screen washing applications and for spreading material evenly over screens they have also been used successfully for foam suppression, conveyor belt washing, and dust control at chutes and hoppers.

Manufactured in 5 different colours with each colour denoting a different orifice size 3mm (grey), 5mm (green), 7mm (blue), 9mm (yellow), and 11mm (red).

A steady, fan shaped water curtain, with pressures from 0.5 to 3.5 bar gives effective washing. In practise it has been found that nearly always, better washing can be achieved with lower water pressures.
The following can be taken as a guide: -

Small size material:- low water pressure, large water quantity – use 9mm or 11mm orifice
Large material size: - high water pressure, medium water quantity – use 5mm or 7 mm orifice.
All nozzles have 3/4” BSPT male thread.
Longwall Shearer Drum Nozzles & Staple

The Stainless Steel Shearer Drum nozzles are manufactured with a built-in strainer to protect against blockage. Each spray is precisely positioned in the shearer drum to reduce airborne dust generation and minimise the risk of frictional ignition.
The nozzle is simply but firmly retained by a stainless steel staple which ensures quick nozzle replacement.

Long - Throw Nozzles

These brass nozzles are useful where a powerful, cohesive jet is needed for a cleaning or fire fighting or similar application.
Two sizes are available: -

1. 50 mm overall length , 4.5 mm orifice
2. 150 mm overall length, 6.3 mm orifice.

Both nozzles have 3/4” NPT female thread.

Emulsion Nozzles

Emulsion Nozzles are used to spray water-based emulsion on roads and footpaths. They are normally mounted on a spray bar or a hand lance. Body is manufactured from cast brass with machined threads while cap is machined from brass.
Inlet is 3/8” BSP female.
Adjustable Emulsion Nozzles

These are a larger version of the Emulsion Nozzle having a cast bronze body with machined threads. The adjustment needle is machined brass.
Used on spray bars where it is desirable to have fine adjustment of the spray output or to be able to turn-off the spray completely.
Inlet is 1/2” BSP female.
