V4 UNIVERSAL VANE FLOW CHARTS
Values shown in both charts are nominal. If normal flows exceed actuation rates by
less than 10%, custom vanes are recommended. Figures are based on standard
vertical installation in a 1-1/2˝ thredolet in a horizontal run of pipe.

Note: Actuation rates are based on cold water at a specific gravity of 1.0. For fluids of different specific gravity, actuation rates may be approximated by dividing the rate
shown by the square root of the specific gravity.

approximations.
