Self-operated Control Valve

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.

• 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.
• All flow display values are randomly calibrated flow rates on the test bench (in m³/h).
• It completely resolves the contradiction of large pressure difference at the near end and small pressure difference at the far end.
• It overcomes the phenomenon of uneven cold and heat in the system and improves the quality of heating (or cooling) supply.
• It reduces design workload, eliminating the need for complex pipe hydraulic calculations.
• It reduces the system's circulating water volume and lowers system resistance.
• It eliminates the need for flow redistribution work when switching heat sources in multi-heat-source pipe networks.
