200X Water Pressure Reducing Valve is mainly used in water pipelines to control and regulate the main valve outlet pressure. It can ensure the outlet pressure sustain at a certain value and do not change when the inlet pressure varied or the flow rate varied.
Product Simple Specification
The valve maintains a preset downstream pressure, regardless of upstream pressure or flow fluctuation. The main valve is controlled by a pilot valve which makes the main valve modulating to maintain the downstream pressure.
Pressure Rating: PN10. PN16. PN25/Class150
Size Range: DN20mm-DN800mm (3/4" - 32")
Test and inspection: GB/T 13927 API598
