Balance valve for the occasion

In a boiler room or chiller room, multiple units are typically installed in parallel. However, due to varying resistance between these units, the flow through each can become imbalanced, preventing them from operating at their maximum capacity. To address this, a balancing valve (as shown in Figure 1) should be installed on each unit. This ensures that each device receives the designed flow rate, allowing it to function efficiently and safely. In thermal power stations or centralized boiler rooms that supply heat to multiple heat stations, proper water flow balance is essential. To achieve the required flow for each thermal loop, a balancing valve should be placed on the return pipe of each loop. Additionally, to ensure that the secondary loops receive the correct design flow, balancing valves must also be installed on the secondary loop sides within each heat station. For district heating networks, where a single boiler room or heat station supplies several buildings, flow distribution can become uneven. This often occurs because buildings located closer to the heat source may receive excessive flow, while those farther away get too little. To prevent this, balancing valves should be installed at the entrance of each main pipeline and individual building, ensuring even flow distribution throughout the network (see Figure 3). In complex heating or cooling pipe systems within a building, it's crucial to maintain balanced flow across all risers and branches. To achieve this, balancing valves should be installed along the main pipes, secondary pipes, and risers (including branch lines), as illustrated in Figure 4. This helps maintain consistent performance and energy efficiency across the entire system.
