200x Pressure Reduce Valve
200X Pressure Reducing Valves are automatic control valves designed to maintain a constant downstream pressure regardless of upstream pressure or flow fluctuations, ensuring safe and stable operation in water supply and industrial piping systems.
Overview
The 200X Pressure Reduce Valve is an intelligent hydraulic control valve that uses the self-energy of the fluid to automatically regulate and stabilize downstream pressure. It ensures a constant outlet pressure even when inlet pressure or flow rate varies.
Working Principle
The valve operates through a pilot-controlled system. The pilot valve senses downstream pressure and modulates the opening of the main valve accordingly. When downstream pressure exceeds the preset value, the main valve closes proportionally; when pressure drops, the valve opens to restore the set pressure.
