ABN A5 Actuator for AB-QM, On/Off
The ABN A5 on/off thermal actuator has been specifically designed for use with AB-QM valves DN10-32/½-1¼ inch in heating and cooling applications. The actuator can be controlled with an on/off or PWM controller which is provided either by a room thermostat or by a central direct digital control (DDC) system.
Actuator ABNM A5 LOG/LIN
The ABNM A5 0-10V thermal actuator has been specifically designed for use with AB-QM valves DN10-32/½-1¾ inch in heating and cooling applications.Control is done by a 0-10 V signal, which isprovided either by a 3rd party room thermostator, in most cases, by a central direct digitalcontrol (DDC) system. The actuator converts the 0-10 V signal into a proportional actuator travel, which can be either linear (ABNM A5 LIN) or logarithmic/equal percentage (ABNM A5 LOG).For fan coil unit or chilled ceiling application choice of logarithmic version is recommended (water to air heat exchanger). The result will be linear system response and thus optimal room temperature control.
Thermal Actuator TWA-Q
Danfoss thermal actuator TWA-Q is used with Danfoss Pressure Independent Control Valves (PICV) type AB-QM DN10-32. The actuator can be controlled with an on/off controller, pulse width modulation (PWM), or switch. These provide a cost effective solution for the control of hot and /or chilled water for fan coil units, small reheaters and recoolers in temperature control systems.
Thermal actuators TWA-Z
Danfoss thermal actuator TWA-Z is used with Danfoss automatically balanced combination valves type AB-QM. The actuator can be controlled with an on/off controller, pulse width modulation (PWM), or switch. These provide a cost effective solution for the control of hot and /or chilled water for fan coil units, small reheaters and recoolers in temperature control systems.
