OEM 200X PRV Pressure reducing valve PN16 ductile iron material Suppliers, Factories
Product Description
Technical Specifications
Characteristics
The 200X reducing pressure valve is controlled by pilot valve without other devices and energy. It is easy to maintain, with high accuracy of pressure control, small influence of inlet pressure and flow, and reliable pressure reduction and stabilization.
Key Advantages
The pressure valve regulator with pilot type two-stage control (pilot valve + main valve), the outlet pressure is little affected by the inlet pressure and flow fluctuation, the pressure stabilization accuracy can reach ± 5%, far better than the ordinary direct-acting pressure reducing valve.
The outlet pressure can still be stabilized at the set value when the flow is increased or decreased, so as to avoid water hammer impact and protect the pipe network and water equipment.
The nominal diameter covers DN50 – DN1000, which can meet the water supply demand of large flow in residential area, plant area, high-rise buildings, municipal pipe network and solve the pain point of "small diameter and insufficient flow" of common relief valve.
Reasonable design of flow passage, small pressure loss, energy conservation and consumption reduction, especially suitable for long-distance and large-flow water conveyance system.

Application Scenarios
The 200X pressure control valve is applied to the water supply network system of high-rise buildings, living areas and urban water supply projects, as well as the fire water system. It can quickly cut off the domestic water supply in case of a fire, and give priority to the fire water demand.

Frequently Asked Questions
A: The 200X valve is a pilot-operated diaphragm control valve. It uses fluid pressure within the pipeline to automatically control and maintain a stable outlet pressure without needing external power sources.
A: The valve comes in standard nominal sizes ranging from DN50 to DN800 (with extended coverage up to DN1000), making it suitable for both commercial building supply and large-scale municipal pipelines.
A: With its pilot-controlled two-stage mechanism, the outlet pressure stabilization accuracy reaches within ±5%, protecting pipe networks and equipment from pressure spikes and water hammer effect.
A: The valve body is available in Ductile Iron, Cast Steel, or Stainless Steel. Internal stems and balls are made of grade stainless steel, paired with high-durability EPDM or NBR rubber seals.
A: Yes, it is widely utilized in fire water management systems. It can prioritize fire suppression supply by regulating domestic water flow instantly in fire emergency scenarios.
A: Yes, our 200X pressure reducing valves are manufactured using investment casting and conform to global standards including BS, API, DIN, and JIS with a guaranteed zero-leakage sealing grade.
