Solenoid-activated spray nozzle

SETO-SD series

SETO-SD series


The SETO-SD series nozzles’ features:

  • Full cone spray pneumatic nozzle producing fine atomization with a mean droplet diameter of 15 – 25 μm (*3).
  • Fast response performance by solenoid activation: intermittent pulse spray at 0.02 sec/shot with a minimum of 0.006 cc/shot is possible.
  • Ideal for coating in small amounts, i.e. protective agent coating, etc.
  • IP65, IP67 (dust-proof and water-proof) structure.
  • Liquid siphon feed type (liquid pressure device is not required). Use with the liquid pressure device is also possible.

*1) Sauter mean droplet diameter measured at compressed air pressure of 0.2 MPa (ca. 2 bar) and liquid pressure of 0.13 MPa (ca. 1.3 bar) for SETO07503R-I+SD, measured at compressed air pressure of 0.3 MPa (ca. 3 bar) and liquid pressure of 0 MPa (liquid siphon feed) for SETO0405R, 07507R or 2210R+SD.
*2) Free passage diameter of liquid inlet.
*3) Measured by Laser Doppler Method.
