Product Description
Danfoss LENO MSV-B — manual (static) double-regulating balancing valve, OEM order code 003Z4131. Manual static double-regulating balancing valve with presetting and integral shut-off for constant-flow hydronic balancing of heating and cooling systems. The digital handwheel presets the branch/riser hydraulic resistance to fix the design flow; the valve also functions as a shut-off with a drain facility. (MSV-B DN 15, External thread, manual balancing valve.) Nominal size DN 15, Kvs 3 m³/h, PN 20, External Thread connection (G ¾ A), DZR brass body, media temperature -20 °C to 120 °C. Net weight 0.67 Kilogram. Genuine Danfoss part; technical data quoted verbatim from store.danfoss.com (code 003Z4131). OEM P/N 003Z4131, EAN 5702420096384. 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 15 branch or riser. Confirm nominal size (DN 15), Kvs (3 m³/h) and connection (External Thread G ¾ A) 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.
