400The flow control valve is used to control the flow of the pipeline and prevent the pipeline flow from exceeding high through the flow limiting function;
The control valve is equipped with a set of flow orifice device. When the pipeline flow changes, the pressure difference through the orifice plate also changes correspondingly. The pressure difference is fed back to the flow guide valve through the control pipeline, so that the opening of the guide valve changes correspondingly, so that the opening of the main valve also changes accordingly, so that the flow through the pipeline reaches dynamic balance;
By turning the adjusting screw on the guide valve, the set flow range can be adjusted, and the set flow rate can be increased by clockwise rotation, and the set flow rate can be decreased by counterclockwise rotation;
Each diameter flow valve is equipped with multiple orifice sizes, and the orifice size is rotated according to the flow range used on site.
