Danfoss AB-QM DN 250 pressure-independent balancing & control valve, flanged (EN 1092-2), PN 16

Danfoss AB-QM DN 250 (003Z1708) — 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 Flange (EN 1092-2). Valve body W.Nr.1.4027. PN 16, nominal flow 300 m³/h, media temperature -10 °C to 120 °C (media). Supplied with test plugs. OEM designation "AB-QM, DN 250, pressure independent balancing and control valve". OEM P/N 003Z1708. Technical data quoted verbatim from store.danfoss.com (code 003Z1708). Used in commercial refrigeration, provision-room cooling and reefer plant rooms across HFC, HFO and CO2 (R744) refrigerants.
