MAKING MODERN LIVING POSSIBLE
PRESURE INDEPENDENT BALANCING AND CONTROL VALVE AB-QM
• automatic balancing of heating and cooling systems
• heating comfort regulation free from pressure fluctuations in the system
• good solution in every situation
AB-QM
is a modern solution which enables achieving and keeping
hydraulic balance in every cooling or heating system. As
a result AB-QM provides constant heating comfort in
a building despite fluctuations of available pressure in
the system. AB-QM is a new generation balancing valve
of Danfoss and can be used in two ways: alone, as an
automatic flow limiter, or with an actuator as a combination Vvariable flow system Constant flow system
of a flow limiter with control valve AB-QM valves and fan-coils
