Description
200X Pressure Reducing Valve
The 200X pressure reducing valve is an intelligent control valve that utilizes the medium itself to automatically regulate and stabilize pipeline pressure. It is widely used in domestic water supply, fire protection systems, and various industrial water supply networks.
By adjusting the pressure-reducing pilot valve, the outlet pressure of the main valve can be precisely set and maintained. Even when the inlet pressure or flow changes, the outlet pressure remains stable at the preset value. This ensures safe, reliable, and consistent operation while meeting system requirements for pressure reduction.
Key Features:
-
Intelligent hydraulic control for automatic pressure regulation
-
Stable outlet pressure, unaffected by inlet pressure or flow fluctuations
-
Adjustable set value to meet different application needs
-
Reliable performance and long service life
-
Applications: Domestic water supply, fire protection, industrial water systems
