AB-QM
The valve will ensure the stated flow in the calculator, if the pressure loss over the component is within the following intervals:
DN10-20: Δp = 16-600 kPa
DN25-32: Δp = 20-600 kPa
DN40-100: Δp = 30-600 kPa
For pump dimensioning, expected pressure losses are 15 or 25 kPa in relation to the intervals above
Choosing e.g. a sigma compact DN25, the state flow will be maintained as long as the pressure loss over the component is set within the intervall 16-600 kPa.
Description
AB-QM is a pressure-independent flow limiter and control valve. The valve can be used separately as an automatic flow limiter or as a combined flow limiter and control valve with mounted thermoactuator. The valve is suitable as a flow limiter and control valve in connection with fan coils, cooling ceilings, ventilation systems and 1-string radiator systems. The range covers a flow range from 30 l / h up to 442,000 l / h.
