Product Description
Danfoss USV-I DN 50 PN 16 — manual (static) balancing valve for the risers and branches of hydronic heating and cooling systems; the presetting and isolating partner valve — sets the design flow (setting scale), shuts off and drains the circuit. Presetting fixes the branch flow so design flow is distributed correctly across the network. Kvs 16 m³/h. Maximum differential pressure 150 kPa. Media temperature -20 °C to 120 °C. internal thread connection (Internal thread ISO 7/1; Rp 2). Brass body, PN 16. OEM designation "USV-I, DN 50, Internal thread ISO 7/1; Rp 2". OEM P/N 003Z2151. EAN 5702420082523. Technical data quoted verbatim from store.danfoss.com (code 003Z2151).

Compatibility & Fitment
USV-I is the presetting/isolating partner of the USV pair — fit it with a USV-M measuring valve on the branch. Read the setting scale to fix the design flow; the valve also shuts off and drains the circuit. Select by pipe size (DN 50) and pressure class (PN 16). Confirm code and connection before ordering.
