K-factor nozzles usually refer to the flow coefficient of fire-fighting nozzles. The fire-fighting nozzles manufactured by us comply with international standards and have the characteristics of good spraying effect, large coverage and high fire extinguishing efficiency. It currently occupies a large position in the global building fire extinguishing nozzles .

The flow coefficient of the spray nozzle is represented by k, and the flow coefficient of the spray nozzle can be distinguished by the pipe diameter of the nozzle. Generally speaking, it is 80 for DN15 and 115 for DN20.

The characteristic coefficient K of the nozzle flow rate should conform to: when the nominal diameter of the nozzle is DN15, the wet nozzle is 80±4, and the dry nozzle is 80±6. K=Q ÷(√10×√P) where: Q represents flow rate, L/min, P represents pressure, MPa. For example, the spray head K80 indicates that the spray head with a flow characteristic coefficient of K80 is required.
