To achieve the best indoor climate control with PICVs it is important to use 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® high-accuracy digital actuators
These innovative digital gear actuators are designed to be directly connected to Building Management Systems (BMS) using BACnet or Modbus bus-communication. This enables a whole new dimension to HVAC control, offering designers, system integrators and building owners many features and benefits which you can read about here:
Danfoss NovoCon® digital actuator
Danfoss NovoCon® digital actuators connect heating and cooling systems to a Building Management System (BMS) enabling smart, Internet of Things, solutions.
AME and AMV modulating gear actuators
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
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.
Following the introduction of AB-QM 4.0 a new thermal On/Off actuator will be launched soon. The new TWA-Q is an IP54 actuator with extended stroke, fitting to all AB-QM valves from sizes DN10 up to DN32.
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.
Danfoss PICV review
We've asked some of our Global customers about their experience with AB-QM pressure independent balancing & control valves. Watch the video where they explain their benefits and why they have converted from conventional balancing solutions to PICVs.
