Overview
The 200X Pressure Reducing Valve is an intelligent hydraulic control valve that automatically regulates and stabilizes downstream pressure using the energy of the conveyed medium itself, without external power.
It is widely used in domestic water supply, fire water supply, and industrial water systems, ensuring a constant outlet pressure regardless of fluctuations in inlet pressure or flow rate.
This valve provides accurate pressure reduction, stable performance, high safety, and long service life, making it an ideal solution for water pressure control in municipal and industrial pipelines.
Product Description
The 200X pressure reducing valve operates through a pilot control system. By adjusting the pilot valve, the outlet pressure of the main valve can be precisely set to the required value.
Once set, the valve automatically maintains the downstream pressure at a fixed level, even when inlet pressure or flow rate changes.
The valve features high regulation accuracy, reliable sealing performance, and convenient installation and adjustment.
For pipelines DN450 and below, the diaphragm-type structure is recommended. For DN500 and above, a piston-type structure is suggested to ensure strength and operational stability.

FAQ
A: It uses a pilot-controlled hydraulic system to automatically regulate and maintain a fixed downstream pressure using the medium’s own energy.
A: No. Once set, the outlet pressure remains stable regardless of changes in inlet pressure or flow rate.
A: No. The valve operates fully automatically without electricity or pneumatic power.
A: It is designed mainly for clean water and similar water-based media.
A: Yes. The outlet pressure can be easily adjusted by setting the pilot valve according to system requirements.
