Danfoss LENO MSV-D (003Z7004) — manual (static) presetting double-regulating balancing valve, DN 32, PN 20, for hydronic heating and cooling circuits. The MSV-D combines presetting, shut-off and two test plugs in one body: the presetting scale sets the design kVS so the branch flow is fixed at commissioning, the integral shut-off (leakage Rate A, ISO 5208) isolates the branch, and the test plugs allow differential-pressure/flow measurement. Fully-open kVS 18 m³/h; valve body cW 617N dezincification-resistant brass; medium temperature -20–120 °C; connection G 1¼" internal thread (Internal thread ISO 228/2). OEM P/N 003Z7004, EAN 5702424617868. Technical data quoted verbatim from store.danfoss.com (code 003Z7004).

Danfoss LENO MSV-D static balancing valve for DN 32 branches, PN 20. Size by the design flow and set the presetting to the calculated kVS (fully-open kVS 18 m³/h). Confirm the connection (G 1¼" internal thread, Internal thread ISO 228/2) and pressure class (PN 20) match the pipework. Use the test plugs with a differential-pressure/flow meter for commissioning. Where automatic differential-pressure control is required instead, pair an ASV-PV controller with an ASV-D partner valve. Genuine Danfoss part — specify order code 003Z7004.
