Fire Foam Sprinkler Head with Factory Price
Introduction:
The reticular foam nozzle (PTW series) is the specialized unit to form and spray air foam, which is mainly used in low expansion extinguishing system. Foam proportionate system supply foam solution for these nozzles. When foam solution was conveyed to nozzles by pipelines, the nozzle inhales air at outlet to make foams and put out fire.
Parameter:
Model | Working Pressure (MPa) | Flow (L/S) | Flow Coefficient | 3m Height Spray Diameter (m) | Thread Size |
PTW1.0 | 0.3~0.5 | 1.0 | 30 | ≥3 | R 1/2" R 3/4" R 1" |
PTW1.2 | 1.2 | 36 | |||
PTW1.5 | 1.5 | 45 | |||
PTW1.75 | 1.75 | 53 |
Working Principle:
When pressurized foam solution flows through the cavity of the nozzle, its pressure will be
reduced because of throttling. That will result in vacuum and inhale air. The foam solution
then become foams after dispersed by nozzle.
