Values shown in both charts are nominal. If normal fl ows exceed actuation rates by less than 10%, custom vanes are recommended. Figures are based 
on standard vertical installation in a 1½  " thredolet in a horizontal run of pipe.

Actuation rates are based on cold water at a specifi c gravity of 1.0. For fl uids of diff erent gravity, actuation rates may be approximated by dividing 
the rate shown by the square root of the specifi c gravity.
