Balancing Valves

When analyzing the overall energy distribution of most facilities, HVAC systems consistently represent the largest share of total energy consumption. Achieving an efficient HVAC system does not depend solely on installing high-efficiency chillers and boilers. A critical factor in translating this efficiency into real performance lies in properly balancing the pressurized closed-loop circuits that connect these energy sources to end-user spaces.
In a typical HVAC system, closed-loop circuits are initially pressurized to an optimal design pressure and flow rate. Heating or cooling fluid is distributed from the boiler or chiller to terminal units such as radiators or fan-coil units located in occupied rooms. Within these spaces, room thermostats and actuators continuously open and close the terminal units based on user demand. This random and dynamic behavior causes fluctuations in flow and differential pressure across the network, leading to hydraulic imbalance and significant energy inefficiencies.

As a premium partner of the world-leading brand Danfoss, Smart Age offers a comprehensive range of balancing solutions, including manual balancing valves (DRV), delta-P control valves, butterfly valves, automatic pressure controllers and Pressure Independent Control Valves (PICV), known as AB-QM in the Danfoss product range.
While traditional HVAC systems may include conventional balancing valves, achieving precise flow control without disturbing system pressure remains a major challenge. In such systems, valve authority is typically limited to around 50%, restricting controllability and overall efficiency. To overcome this limitation, Smart Age implements PICV solutions that combine pressure-independent balancing with accurate flow control, granting designers 100% valve authority and ensuring maximum system efficiency. With these valves, complex flow and pressure recalculations become unnecessary, as the differential pressure across terminal units remains constant regardless of system load variations.
