Flat Spray Semi-Fine Fog Nozzles DOVEA series nozzles

Features

• 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.
• Large free passage diameter minimizes clogging.
• Spray angle of 55ﾟ, 70ﾟ, 95ﾟ, or 110ﾟ.

*1) Measured at compressed air pressure of 0.3 MPa and liquid pressure of 0.7 MPa.
*2) Free passage diameter of nozzle orifice.
*3) Measured by Fraunhofer diffraction method.

Applications

For the mass of DOVEA with a longer/shorter pipe, add or subtract the corresponding mass (shown below) for each 100 mm of L1 length, according to Nozzle Thread Size 1. (When the Nozzle Thread Size 1 is 1/4F, mass per 100 mm is 63 g, when 3/8F it’s 85 g., when 1/2F it’s 130 g)
