AB-QM Pressure independent valve



AB-QM is a Pressure Independent Balancing and Control Valve, which limits the maximum flow, and at the same time function as a control valve operated by different types of Danfoss actuators. As result the system is temperature controlled as well as hydronically balanced.

AB-QM can be set to a precise design value and thereby provide full control over the real conditions in the system.

AME QM push-pull actuators for large AB-QM The AME QM actuators are used with the AB-QM pressure independent balancing and control valve. DN40 to DN100: AME 435 QM DN125 and DN150: AME 55 QM DN200 and DN250: AME 85 QM The actuators automatically adapt the stroke to the valve end positions which reduces commissioning time. They are very flexible actuators, which can be controlled by all types of control signals like voltage, current and 3-point.
AME/V 110/120 NL/X & AMI 140 AMV(E) 110 NL and AMV(E) 120 NL actuators are used 0-10V and 3-point gear actuators that combine with AB-QM (sizes DN10-DN32) for superb control. AMI 140 is 2-point 3-wire actuator used with AB-QM DN10-DN32.
HERO H-piece unit with AB-QM valve The Danfoss HERO connection set with AB-QM valve is a compact and time saving configuration – designed for creating optimal hydronic balance in cooling and heating applications with variable flow (installations incorporating fan coil units (FCU) or chilled beams). Flow is controlled by the AB-QM pressure independent control valve to avoid overflow and reduced efficiency of thermal unit.
TWA-Z Actuators Thermal actuator for Danfoss automatic flow limiter type AB-QM and for valve type VZL.
