Description
Danfoss AB-QM 003Z0706 & 003Z0716
Danfoss AB-QM was the first of its kind control valve for HVAC heating and cooling applications. It is a control valve with automatic flow limitation and built-in differential pressure control functioning over the control valve. Two or four pipe heating and/or cooling systems are characterized by changing conditions due to valves opening and closing depending on the need for heating or cooling. This continuously causes flow and differential pressure changes. Without proper measurements, such systems suffer from uneven heat distribution, and poor energy inefficiency and are very difficult to the commission. By adding an actuator, the valves function as flow-limited control valves, automatically balancing the system and providing the best possible indoor comfort and energy efficiency. The commissioning of the system is a lot easier, all valves only need to be set to the design flow before the actuators are mounted. Danfoss offers a broad range of pressure-independent balancing and control valves and matching actuators. Features and benefits Improved indoor comfort Energy savings Reduced maintenance costs |
