Description

The AB-QM valve equipped with an actuator is a control valve with full authority and an automatic balancing function / flow limitation. Typical applications are: Temperature control with permanent automatic balancing on terminal units (chillers, air-handling units, fan coils, induction units, radiation panels and heat exchangers). Description The precise flow control performance of the AB-QM with a Danfoss actuator provides increased comfort and superior Total Cost of Ownership because of savings made on: • Efficient energy transfer and minimal pumping costs since there are no overflows at partial loads because of the exact pressure independent flow limitation. • Smaller pump investments and lower energy consumption as the pump head needed is lower than in the traditional setup. With the built in test plugs it is easy to troubleshoot and find the optimal setpoint for the pump. • Reduced movements of the actuator since the built-in differential pressure controller ensure the pressure fluctuations do not influence the room temperature. • Achieving a stable temperature in a room leading to a lower average temperature at the same comfort level. • Minimal flow complains, as the valve performs as designed. • Minimal blockage complains, as the membrane design makes AB-QM less susceptible to blockage than a cartridge type constriction. • Trouble-free segmentation of the building project. When sections of a project are finished they can normally not be handed over to the customer with a fully functional HVAC installation. However the AB-QM with a Danfoss actuator will automatically control.
