Compatibility & Fitment
Select the orifice by pipe size (DN 125); the Kvs value fixes the flow/pressure-drop relation used to compute circuit flow with a differential-pressure measuring instrument. For large-diameter risers and mains where a measuring balancing valve is not fitted. Confirm DN and flange class before ordering.
