Danfoss USV-S DN 15 PN 16 manual static balancing valve, internal thread (003Z2231)

Part Number
003Z2231 · HS 8481.80

Danfoss USV-S DN 15 PN 16 — manual (static) balancing valve for the risers and branches of hydronic heating and cooling systems; the compact combined presetting and shut-off balancing valve (operating elements and connections within a 90° arc). Presetting fixes the branch flow so design flow is distributed correctly across the network. Kvs 1.6 m³/h. Maximum differential pressure 150 kPa. Media temperature -20 °C to 120 °C. internal thread connection (Internal thread). Brass body, PN 16. OEM designation "USV-S, DN 15, Internal thread". OEM P/N 003Z2231. EAN 5710104082806.
