The function of the electric flow v

The function of the electric flow valve is to maintain the constant flow when the pressure difference between the inlet and outlet of the valve changes, so as to maintain the constant flow of the controlled object (such as a loop, a user, a device, etc.) in series with it. The application of flow valve in the pipe network can directly set the flow according to the design. Under the action of water pressure, the valve can automatically eliminate the flow deviation caused by the residual pressure head and pressure fluctuation of the pipeline. There are many names of flow valve, such as self operated flow balance valve, constant flow valve, dynamic balance valve, etc. Each type of flow valve has different structure, but its working principle is similar.
