DANFOSS ABQM PRESSURE INDEPENDENT CONTROL VALVES

 

The AB-QM has a linear control characteristic.

The AB-QM ispressure independent which means that the control characteristic is independent from the available pressure andisnot influenced by a low authority.

The flow limitation on the AB-QM is achievedby limiting the stroke and the Danfoss actuators calibrate to the stroke of the valves. This means that the AB-QM keeps its linear characteristic independent of the setting or differential pressure.

Because of the predictable characteristic the actuators onthe AB-QM can be used to change the response from linear to logarithmic (equal percentage). That makes the AB-QM suitable for all applications, including AHUs, where the equal percentage characteristic is needed to get a stable control loop. The actuators can be switched from linear to logarithmic by changing a dip switch setting on the actuator.
