The valve is installed in the situation where the water pipe line needs to control the flow, so as to keep the predetermined flow rate unchanged, the excessive flow is limited to a predetermined value, and the upstream high voltage is reduced to the lower pressure. Even if pressure changes upstream of the main valve, it will not affect downstream flow.
It is easy to install and easy to use. The control part has no complicated electric sensing mechanism. It is not easy to break down, set simple, and automatically complete the adjustment function after setting. No manual operation or other power source is required.
The valve's guide valve obtains the differential signal from the orifice and controls the switch of the main valve. When the pipeline flow rate is greater than the set flow,the main valve is smaller, and the valve disc is stable when the flow is restored to the original setting value.
