Describe
Structure and use
 
The valve is composed of a main valve 4, a needle valve 6, a flow regulating valve 3, a pilot valve 2, a ball valve 1 and a pressure gauge 5. The flow control valve is placed in the water supply line. The fixed flow rate of the upper pilot valve 2 and the flow regulating valve 3 of the regulating valve can be set first, so that the flow rate through the main valve can be kept constant, and the flow will not be affected even if the upstream valve changes.
