Flow Curves

Flow Curves: Pressure loss versus flow data as determined by
independent approval agencies. (See Notes below)
HOSE CONNECTION DUAL CHECK
HBDUC

PRESSURE LOSS (PSI)

FLOWRATE (GPM)

LAB FAUCET DUAL CHECK

LFDUC

PRESSURE LOSS (PSI)

FLOWRATE (GPM)

PRESSURE LOSS CURVE NOTES:
1. Flow curves directly reflect data collected by independent approval laboratories.
2. Flow curves shown were recorded with butterfly shut-off valves. Flow curves with gate valves are
slightly lower. Contact factory for more information.
3. All data points are based on increasing flow data, from zero GPM to rated flow (opening curve)
4. For higher flow rates/pressure loss information - contact factory.
