Steam-Driven Nozzles/ Full Cone Spray JOKIJet series nozzles

Thread standard - Pipe conn. size Rc1/2 Standard pressure -
Spray angle - Spray capacity 10–1,200 ℓ/hr (*1) Supply air type Steam
Liquid feeding system Liquid pressure Mean droplet diameter - Air consumption -
Air pressure - Free passage diameter 1.1–4.2 mm (*2)


• Innovative pneumatic spray nozzle using steam instead of compressed air to produce fine (semi-fine) atomization.
• Great savings on running costs realized by utilizing steam from an existing boiler facility.

*1) Spray capacity measured at steam pressure of 0.1–0.6 MPa and liquid pressure of 0.1–0.5 MPa.
*2) Free passage diameter of liquid inlet.

To control the spray out of the JOKIJet nozzles, control by steam pressure and spray capacity is recommended.
Attempts to control the spray by controlling the steam pressure and liquid pressure may not allow stable spray control.
