Danfoss AB-QM TX AHR Expo 2009

AB-QM, Pressure Independent Control Valve

These valves can be used separately for automatic flow limiting or, when fitted with an actuator, can serve as combined flow limiter and control valve. Setting is extremely user friendly and reliable. AB -QM valve applications include balancing and controlling terminal units such as fan-coils, chilled ceilings, and air handling units. Setting is made quick and easy for the installer. Fitting with a Danfoss actuator upgrades the AB -QM to a full-function control valve for both temperature control and flow balancing.
