Highlight: Self-operated Control Valve
Product introduction:
The self-operated flow control valve (self-operated balancing valve) is an intuitive and simple flow regulation and control
device. When applied in a pipe network, this valve can directly set the flow rate according to the design. Driven by water,
the valve can automatically eliminate flow deviations caused by residual pressure heads in the pipeline and pressure
fluctuations. Regardless of changes in system pressure, it maintains the set flow rate constant. These functions enable the
pipe network flow regulation to be completed in one go, turning the pipe network adjustment work into a simple flow
distribution task and effectively solving the hydraulic imbalance of the pipe network.

| Sealing Test | 1.1～1.76 |
| Medium Temperature | 0-150℃ | |
| Operating Pressure Difference Range | 20-600Kpa | |
Product features:
1. The flow rate can be set according to design or actual requirements, and it can automatically eliminate pressure
difference fluctuations in the system to maintain a constant flow rate.
2. All flow display values are randomly calibrated flow rates on the test bench (in m³/h).
3. It completely resolves the contradiction of large pressure difference at the near end and small pressure difference at the
far end.
4. It overcomes the phenomenon of uneven cold and heat in the system and improves the quality of heating (or cooling)
supply.
5. It reduces design workload, eliminating the need for pipe [Note: The original text is incomplete here; it is recommended
to supplement it as "eliminating the need for complex pipe hydraulic calculations" or other complete meanings according to
the context].
6. It reduces the system's circulating water volume and lowers system resistance.
7. It eliminates the need for flow redistribution work when switching heat sources in multi-heat-source pipe networks.
