The best results in indoor climate control are achieved by using the best possible actuators. The faster and more accurate the actuator responds to the control signal, the better the result.

Danfoss offers a wide variety of actuators fitting the AB-QM Pressure-Independent Balancing and Control valve.

NovoCon® S

This innovative digital gear actuator with bus communication is designed to be directly connected to Building Management Systems (BMS) using BACnet or Modbus communication. It offers many features and benefits which you can read about here.

AME and AMV

To achieve the best control performance with analog control signals, gear actuators should be used. These actuators control the position of the valve opening in a very accurate way.

AME gear actuators are controlled by a 0-10V or 4-20mA signal, while AMV actuators are controlled by a 3-point signal (open/neutral/close).

To achieve maximum control performance, geared actuators for AB-QM are equipped with automatic valve stroke detection.

TWA, ABN and ABNM

Thermal actuators provide a cost-efficient control solution for the AB-QM valves. The basic principle of these actuators is based on thermal expansion of a wax element. TWA-Z and ABN A5 actuators are controlled by an On/Off signal of a temperature controller, either heating the wax or not. 
ABNM A5 actuators are controlled by a 0-10 Volt modulating signal of a temperature controller. The 0-10 V signal allows more accurate control possibilities.

Features and benefits

Broad product range

With actuators available for all AB-QM dimensions (DN 10 – 250), for all commonly used control signals (on-off, 0-10V, 4-20 mA, bus communication) and functional principles (thermal, analog gear, digital gear), there is always an AB-QM / Actuator combination that corresponds to the project requirements.
