Danfoss AB-QM DN 50 pressure-independent balancing & control valve, external thread connection, for NovoCon M actuator

Danfoss AB-QM DN 50 (003Z1771) — pressure-independent balancing and control valve (PICV) for heating and cooling distribution. The integral differential-pressure controller holds the flow through the settable orifice constant regardless of pressure fluctuations in the network, combining automatic balancing, flow limitation and modulating control in one valve. Connection External Thread. Valve body Grey cast iron EN-GJL-250 (GG-25). PN 16, nominal flow 12.5 m³/h, media temperature -10 °C to 120 °C (media). Supplied with test plugs. Designed for the Danfoss NovoCon M digital actuator (ordered separately). OEM designation "AB-QM NovoCon DN 50, with three test plugs, pressure independent balancing and control valve, to be used with NovoCon M". OEM P/N 003Z1771. Contains lead per the REACH candidate list. Technical data quoted verbatim from store.danfoss.com (code 003Z1771). Used in commercial refrigeration, provision-room cooling and reefer plant rooms across HFC, HFO and CO2 (R744) refrigerants.
