Danfoss AB-QM DN 25 standard-flow pressure-independent balancing & control valve, without test plugs

Danfoss AB-QM DN 25 — pressure-independent balancing and control valve (PICV) for the terminal branches of heating and cooling systems. A built-in differential-pressure controller keeps the flow through the settable orifice constant regardless of pressure fluctuations elsewhere in the network, so each terminal delivers its design flow without manual re-balancing; the presetting dial fixes the maximum flow (20 %-100 % of nominal) and the valve also acts as a shut-off. DZR brass CuZn36Pb2AS (CW 602N) body, External thread ISO 228/1 G 1 ¼A connection, AB-QM 3.0, PN 16, nominal flow 1.7 m³/h, control differential pressure 20 KPa to 600 KPa, seat leakage Class III with the recommended actuator, media temperature -10 °C to 120 °C. Supplied without test plugs. Actuator connection M30 x 1.5. OEM P/N 003Z1204. EAN 5710104029849. Technical data quoted verbatim from store.danfoss.com (code 003Z1204).
