  Structural Characteristic&Purpose.
  
  This series pressure reducing valve is a new type regulating valve which adopts piston to replace the diaphragm. The performance is reliable and it's can be used for a long time. The down pressure can be adjusted according to the requirement, and it can be set at a fixed pressure in the application, which won't be changed as the fluctuation of the up pressure and the flowing rate.
