Execution:
- made in accordance with PN-EN-671-2
- a nozzle with a plastic valve head
- regulation of the stream type and efficiency takes place by turning the gripping part of the nozzle made of ABS plastic in red RAL 3000
Nozzles allow you to adjust the settings in the following positions:
- closed
- dispersed water stream
- compact water stream
HYDRAULIC PROPERTIES
Working pressure: from 0,2 MPa to 1,2 MPa
Diffused conical water stream – not less than 45 degrees.
| Flow rate /efficiency/ | Pressure | Dispersed stream | Compact stream |
| Equivalent diameter 13 mm | 0,2 MPa | 172 l/min | 155 l/min |
| 0,4 MPa | 244 l/min | 220 l/min | |
| 0,6 MPa | 299 l/min | 270 l/min | |
| Factor K | 122 | 110 | |
| Effective coverage range of the water stream /+ the length of the hose 15 or 20 m/ | |||
| Equivalent diameter 13 mm | 0,2 MPa | 8,1 m | 10,5 m |
Attention! The dependence of the flow rate Q on the pressure P is given by the equation: Q = √10P, where Q is expressed in liters / minute and P in megapascals.
