The pressure independent balancing and control valve means that the control characteristic is independent from the available pressure.
The precise flow control performance of the AB-QM with a Danfoss actuator provides increased comfort and superior Total Cost of Ownership.
They regulate and maintain a constant flow to the coil as water pressure in the system varies with the changing loads.
This delivers better comfort, increases energy efficiency, reduces actuator operation and reduces expensive call backs.
Pressure independent valves allow the system to perform better.
With a pressure-dependent valve, as the pressure in the system changes, the flow through the valve changes.
By incorporating an integral automatic balancing component, pressure- independent valves compensate for pressure changes and maintain a constant flow over a wide range of pressures.
