Spillback nozzles(with variable flow) SPB series nozzles

Pipe conn. size Rc1/2 Spray angle 60゚, 85゚, 95゚, 100゚, 105゚, 120゚, 125゚, 127゚, or 130゚ Mean droplet diameter 99–237 μm
Strainer Not included Standard pressure 2.0 MPa Spray capacity 2.00–20.0 ℓ/min
Air consumption - Free passage diameter 1.3–3.0 mm


• Variable capacity hollow cone spray nozzle generating fine atomization with uniform spray distribution.
• The turn-down ratio of spray capacity is 1:10.
• The variation in spray droplet sizes is minimized.
• SPB series nozzles are suitable for gas cooling where the flow rate or gas temperature varies.


• Cooling: Incinerators (flue gas desulfurization), cement factories, glass factories, blast furnaces, iron works, blast furnaces (dry dust catcher)
• Moisture control: Blast furnaces (water spraying to hot blast stove)

Industries in which this nozzle is used

• Pollution control
