1Suggested flow range applicability (BS7350)
If used with measuring manometers different from those proposed by VIR please verify that sensibility of the measuring device is compatiblewith indicated minimum flow (see flow measurement paragraph)
Formula linking flow Q (in l/s) and ∆pmeasured at test points (in kPa). Kvdepends on handwheel position asindicated on table.Minimum flow that can be measuredfor each diameter may be calculatedby using in the formula minimum ∆pthat can be measured by usedmanometer.Valves are anyway designed for bestperformances when used on rangepreviously suggested and as indicatedby BS7350.

Formula linking flow Q (in l/s) and theoretical valve headloss ∆p (in kPa).Kv depends on handwheel position as indicated on table.
To obtain the best performances valve must be installed on a pipe with its samenominal size preceded and followed by straight pipe lengths as per figureindications.
