Solenoid-activated Spray Nozzles SETO-SD series nozzles

Thread standard - Pipe conn. size Rc1/8 Standard pressure -
Spray angle - Spray capacity 0.9–26.4 ℓ/hr Supply air type Compressed air
Liquid feeding system Liquid pressure, Liquid siphon Mean droplet diameter 15–25 μm (*1, *3) Air consumption 36–200 ℓ/min, Normal
Air pressure 0.2–0.4 MPa Free passage diameter 0.3–1.0 mm (*2)


• 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 and liquid pressure of 0.13 MPa for SETO07503R-I+SD, measured at compressed air pressure of 0.3 MPa 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.


• Spraying release agent for metal molds
