Danfoss AF-range impulse tube set (OEM designation "Impulse tubes for AFPB (-F) PN40 50"). The impulse tubes connect the diaphragm chamber of a Danfoss self-acting AF-range pressure/flow controller actuator to the pressure-sensing tapping(s) on the pipework, transmitting the pipe pressure to the actuator so it can hold the set differential pressure or flow. This set is matched to the AFPB (-F) controller on valve size DN 50 at PN 40. Tube outer diameter 10 mm; union connection G 1/4; material Stainless steel. Permissible medium: District heating/cooling circulation water. OEM P/N 003G1360. EAN 5702421812105. Technical data quoted verbatim from store.danfoss.com (code 003G1360).

Impulse tubes are ordered to match the controller Type and the valve size/pressure class. This set fits AFPB (-F) controllers at valve size DN 50, PN 40. Confirm the controller Type, valve DN and PN against the AF-range data sheet before ordering — impulse tube length and fittings differ between controller families (AFQ, AFP/AFPB, AFPQ, AFPQ4/AVPQ).
