Model 47-08 flow rate control valve is used to adjust and maintain the preset max. Flow rate no matter how pressure varied inside the pipe. It can prevent the flow rate over the max flow rate limitation. It is hydraulic pressure control inside the pipe and is a diaphragm valve controlled by pilot, which can sense the pressure difference at the both sides of the downstream flow limit orifices plate and balance the pressure both sides, automatically adjust the open degree to maintain the flow rate at a certain range.
The adjustable pole of pilot can slightly adjust flow rate.
