SPECIFIC GRAVITY CORRECTION
To determine the actuating flow rates for liquids other
than water (approximate viscosity of 20 centistokes or
less), a specific gravity correction factor must be applied
to the water flow rates given in the table. For gas/air
applications, consult factory.

Model F10 Example:
The maximum adjustment for an increasing flow rate on
a Model F10 with a liquid specific gravity of .70 in an 8"
line is: 230 GPM x 1.20 = 276 GPM.
Model F50 Example:
The actuation flow rate of a liquid with specific gravity
of 1.10 on increasing flow for a Model F50 with a 1"
body and an “E” size disc is: 5.5 GPM x 0.95 = 5.2 GPM.
