Performance Curves
Metered Flow vs. Pressure Drop (Through cartridge only)
= No. of Turns From Fully Closed.
The number on each curve indicates the number of complete
turns of the knob or screw adjustment from fully closed.
When the metered flow is 22.5 LPM (6 GPM) and the
adjustment is two complete turns from closed, the pressure
drop will be 13.8 Bar (200 PSI). When the metered flow is
22.5 LPM (6 GPM) and the adjustment is five complete turns
from closed, the pressure drop will be 3.5 Bar (50 PSI).
= No. of Turns From Fully Closed.
The number on each curve indicates the number of complete
turns of the knob or screw adjustment from fully closed (non-
metered flow). When the metered flow is 7.5 LPM (2 GPM)
and the adjustment is two complete turns from closed, the
pressure drop will be 156.9 Bar (2275 PSI). When the
metered flow is 7.5 LPM (2 GPM) and the adjustment is 3.75
turns from closed, the pressure drop will be 56.6 Bar (820 PSI).
