AFQM / AFQM 6
AFQM 6 is a self-acting flow controller with integrated control valve with full authority, primarily for use in district heating systems. The controller closes when set max. flow is exceeded. In combination with Danfoss electrical actuators AMV(E) can be controlled by ECL electronic controllers. The AFQM 6 is pressure independent which means that the control characteristic is independent from the available pressure and is not influenced by a low authority. The controller has a control valve with adjustable flow restrictor, connection neck for electrical actuator and an actuator with one control diaphragm. Control valve AFQM 6 DN40-50 is not pressure relieved.

Intelligent electrical actuator AMEi 6 iNET
AMEi 6 iNET actuator for intelligent network balancing, enables remote adjustment of differential pressure (Δp) setting on AFA 2, AFD 2, AFP 2, AFPA 2, AFPB 2, AFPQ 2 and AFQMP 2 controllers, used in District Heating/Cooling systems.

Changing heat consumption requires changes in heat distribution. Therefore the Δp should be optimised at each branch. With iNET the Δp can be remotely adjusted. Input for pump optimization.
