Product Description
Danfoss USV-M DN 15 PN 16 — manual (static) balancing valve for the risers and branches of hydronic heating and cooling systems; the measuring partner valve of the USV pair — carries the measuring/flow-limitation function and is upgradeable in situ to a differential-pressure (PV) controller. Presetting fixes the branch flow so design flow is distributed correctly across the network. Kvs 1.6 m³/h. Maximum differential pressure 80 kPa. Media temperature -20 °C to 120 °C. external thread connection (External thread ISO 228/1, G ¾A). Brass body, PN 16. OEM designation "USV-M, DN 15, G ¾A; External thread ISO 228/1". OEM P/N 003Z2126. EAN 5702420083513. Technical data quoted verbatim from store.danfoss.com (code 003Z2126).

Compatibility & Fitment
USV-M is the measuring/upgradeable partner of the USV pair — fit it with a USV-I isolating valve on the branch. Select by pipe size (DN 15) and pressure class (PN 16). Upgradeable in situ to a differential-pressure (PV) controller (order the matching PV upgrade part by DN). Confirm code and connection before ordering.
