• Recommended flow range: 2-57 LPM (0.5-15.0 GPM)
• Operating pressure: 1-10 Bar (15-150 PSI)
• Burst pressure safety rating: 52 Bar (750 PSI)
Note: For optimum sprinkler performance when designing a system,
calculate total friction loss to ensure sufficient downstream pressure.
Flow rates are recommended not to exceed 5 PSI loss.
