| Valve Type: | 200X pressure reduce valve | Structure: | Diaphragm type |
| Standard: | BS/API/DIN/JIS | Workmanship: | Investment casting |
| Sealing direction: | Single-directional | Sealing grade: | Zero leakage |
| Temperature: | 0°C < T < 80°C | Operation: | Automatic |
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.
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.

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.

A: It utilizes a pilot-type two-stage control system. The outlet pressure is precisely adjusted by the pilot valve, ensuring minimal fluctuation even when inlet pressure or flow changes.
A: We offer a wide range of sizes from DN50 up to DN1000, catering to both residential and large-scale municipal water networks.
A: Yes, it is ideal for fire water systems. It can prioritize fire water demand by quickly cutting off domestic supply during emergencies.
A: No, the 200X valve is automatic and controlled by the pilot valve using the energy of the flowing medium itself.
A: The valve body is available in Ductile Iron, Cast Steel, and Stainless Steel, with EPDM or NBR seals to suit various temperature and chemical requirements.
A: The standard working temperature range for this diaphragm-type valve is between 0°C and 80°C.
