The pressure regulating valve, also known as the autonomous balancing valve, flow control valve, flow controller, dynamic balancing valve, and flow balancing valve, is a simple and intuitive device for regulating flow. In the network, the flow regulation valve can be set to the desired flow directly according to the design. The valve can automatically eliminate the residual pressure head and pressure fluctuations caused by flow deviations in the pipeline under water action. No matter how the system pressure changes, the set flow remains constant. These functions of the valve allow the network flow regulation to be completed once, turning the network adjustment into a simple flow distribution. This effectively solves the hydraulic imbalance of the network. The flow regulation valve is mainly applied in: water systems such as centralized heating (cooling), enabling the network flow to be allocated according to the needs, eliminating the hydraulic imbalance of the water system, and solving the problem of uneven heat and cold.
