The AB-QM valve with Danfoss actuator for precise flow control brings high comfort and favorable overall operating costs. AB-QM is suitable for offices, hotels, hospitals and buildings where temperature control is required, even in laboratories and research institutes.
Thanks to AB-QM valves, the assembled system no longer needs to be balanced, thus eliminating the complicated step-by-step measurements and time-consuming correction of previously used valves.
The AB-QM system is operated in variable flow mode. The amount of water that is needed at a given time flows to the individual appliances. This makes the whole system more economical.
The AB-QM valve can be used for all air conditioning applications as it can have linear or logarithmic characteristics in conjunction with thermoelectric actuators or electric actuators.
Thanks to the integrated differential pressure regulator, the regulator valve always has 100% authority and therefore always ensures stable regulation. The compact design allows installation in small spaces. For example, fan-coil units.
Calculations of Kv value or authority are not required. Flow is the only parameter needed for valve design. Easy commissioning. Because the AB-QM has two functions - balancing and control- installation costs are halved.
