Compatibility & Fitment

Supplied as the two-valve USV set (USV-M measuring valve + USV-I isolating valve) for one branch. Select by pipe size (DN 32) and network pressure class (PN 16); use the Kvs with the branch design flow to set the required presetting. The USV-M can be upgraded in situ to a differential-pressure (PV) controller. Confirm code and connection against the datasheet before ordering.
