[Made-to-Order] Thick Flat Spray Semi-Fine Fog Nozzles DDA series nozzles

Thread standard - Pipe conn. size Rc1/4–Rc1/2 Standard pressure -
Spray angle 75°–125° (*1) Spray capacity 0.14–57.3 ℓ/min Supply air type Compressed air
Liquid feeding system Liquid pressure Mean droplet diameter 15–200 μm (*3) Air consumption 17–610 ℓ/min, Normal
Air pressure 0.1–0.4 MPa Free passage diameter 2.0–7.0 mm (*2)

Features

• Thick flat spray pneumatic nozzle producing a large volume of semi-fine atomization with a mean droplet diameter of 50 μm or more (*3).
• Liquid pressure type under the liquid pressures of 0.07–0.7 MPa.
• Large turn-down ratio with minimal variation in spray angle.
• Uniform distribution suitable for multiple-nozzle arrangements.
• Thicker flat spray pattern covers wider area.
• Large free passage diameter minimizes clogging.
• Spray angle of 75°, 80°, 100°, 110°, or 125°.

*1) Criteria for spray angle measurement differs depending on nozzle codes.
*2) Free passage diameter of nozzle orifice.
*3) Measured by Fraunhofer diffraction method.

Applications

Cooling: Gas, steel plates, steel pieces, pipes, moldings, etc.

[Steelmaking industry]
Steel making process: Cooling continuous casted steel (bloom, slab short side, billet), cooling roll of casting machine
Rolling mill process: Cooling steel plate on continuous annealing line, roll in heat treatment, and magnetic steel

Industries in which this nozzle is used

・ L1 shows the standard length, which is shortest, and the longest length is 1,500 mm.
・ Pipe connection sizes for air and liquid are the same.
・ Each mass shows DDA with standard length (L1). For longer lengths, add the corresponding mass (listed below) for each 100 mm of length, according to Nozzle Thread Size 1. (When the Nozzle Thread Size 1 is 1/8F, mass per 100 mm is 50 g, for 1/4F it's 80 g, for 1/2F it's 160 g, for 3/4F it's 220 g)
