Danfoss 003Z0303 AB-QM Pressure Independent Control Valve, 3/4

The AB-QM is a versatile device that can be used as an actuated or non-actuated balance valve. AB-QM is a pressure-independent control valve with a built-in, integrated differential pressure regulator. The unique design allows the valve to be selected via required flow versus traditional Cv calculations.
