The danfoss AB-QM is an automatic flowlimiter that can be fitted with an actuator to create a control valve with integrated automatic flow limitation. The valve is extremely compact and is perfectly suited for the high demands of modern cooling and heating systems.
Setting the desired flow on the flowlimiter is extremely easy and can be done without tools. The advanced technology of the AB-QM ensures that the flow in the installation are accurately controlled under all circumstances and independent of the load on the system.
The AB-QM has an integrated differential pressure controller that keeps the pressure across the control valve constant. Because of this, the control valve automatically has an authority of 100% which provides stable and precise control.
