Product Description
Danfoss LENO MSV-BD — manual (static) double-regulating balancing valve, OEM order code 003Z4006. Manual static balancing valve with presetting and integral shut-off for the constant-flow (hydronic) balancing of heating and cooling distribution systems. The digital handwheel presets a hydraulic resistance so the design flow is fixed in the branch or riser; the two integral test plugs allow the differential pressure across the valve to be measured and the flow read off the valve chart (or a Danfoss PFM meter). Drain function and full shut-off are built in. (MSV-BD DN 50, Internal thread, manual balancing valve.) Nominal size DN 50, Kvs 40 m³/h, PN 20, Internal thread ISO 228/1 connection (G 2"), DZR brass body, media temperature -20 °C to 120 °C. Net weight 2.6 Kilogram. Genuine Danfoss part; technical data quoted verbatim from store.danfoss.com (code 003Z4006). OEM P/N 003Z4006, EAN 5702420084107. Used in commercial refrigeration, provision-room cooling and reefer plant rooms across HFC, HFO and CO2 (R744) refrigerants.

Compatibility & Fitment
Manual static balancing valve for constant-flow hydronic balancing of a DN 50 branch or riser. Confirm nominal size (DN 50), Kvs (40 m³/h) and connection (Internal thread ISO 228/1 G 2") against the circuit design; measure flow at the test plugs and preset the design flow. Read flow with a Danfoss PFM meter or the valve chart.
