A 200X Pressure Reducing Valve (PRV) is a hydraulically operated, diaphragm-actuated control valve designed to maintain a steady, pre-set downstream pressure regardless of fluctuations in the upstream (inlet) pressure or flow demand.

Products Description
The adjustable pressure reducing valve is composed of a diaphragm main valve, an angle needle valve, a ball valve, a steel pipe, apressure gauge and a pressure reducing pilot valve, It divides the water flowing through it into upstream and downstream withdiferent pressures, and can supply water to the downstream according to the pressure set by the user (set value s7/8 sourcepressure), and the water supply pressure will not be decompressed due to the fluctuation of inlet pressure and the change of outletflow.
Its primary function is to protect downstream equipment from damage caused by excessive pressure and to maintain a constant, pre-set pressure for optimal system performance.
It works much like a pressure regulator on a scuba tank or a propane grill, but on a much larger scale for industrial and municipal water systems.
Features
• Accurate Control: The pilot-operated design provides stable and precise pressure regulation.
• Adjustability: The outlet pressure can be easily changed in the field without removing the valve from the line.
• Self-Acting: Requires no external power source; operates using the energy from the water system itself.
• Reliability: Simple, robust design with few moving parts leads to long service life.
• Versatility: Available in a wide range of sizes (e.g., 2" to 16") and materials for various applications.
