Pressure regulating valve
Adjustable pressure reducing valve
200X pressure reducing valves automatically 
reduce and regulate a higher inlet pressure to a steady lower downstream pressure, regardless of chaning flow rate and varying inlet pressure.
This valve is an accurate, pilot-operated regulator capable of holding down steam pressure to a re-determined limit. When downstream pressure exceeds the pressure setting of the control pilot, the main valve and pilot valve close drip-tight.
Size: DN50 – DN600
Flange drilling is suitable for BS EN1092-2 PN10/16.
Epoxy fusion coating.

1. Work stable and reliable and big flow pass.
2. Disc open quickly and close slowly without water hammer.
3. High precision reducing regulator with large range.
4. Sealing performance and long service life.
Installation Requirements:
1. Recommend to install exhuast valve in pipe system to make sure the steady working.
2. Pressure of inlet should not less than 0.2Mpa. If it does, the performance will be worse. (Pressure tolerance of outlet will increase.)
