Danfoss ASV-I — adjustment (presetting & measuring) partner valve, OEM order code 003L7643. Adjustment partner valve for the supply pipe of a riser controlled by a Danfoss ASV-P or ASV-PV differential-pressure controller (the controller impulse tube connects here). It carries a setting scale for presetting/flow limitation, allows the flow to be measured and read, and provides integral shut-off, so the riser can be preset, measured and isolated from one point. Used where the terminal (radiator) valves have no presetting facility. (ASV-I DN 25, internal thread, adjustment valve.) Nominal size DN 25, Kvs 4 m³/h, PN 16, Internal thread connection, Brass body, media temperature -20 °C to 120 °C. Net weight 0.646 Kilogram.
