    Description

    42X Direct Acting Diaphragm Type Pressure Reducing Valve 


    Brief Introduction.

    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.

    Field of Application.

    Product Name: Y42X-GVPR12 Direct Action Piston Pressure Reducing Valve.

    Pressure Rating: 1.0- 6.4Mpa
    Nominal Diameter: DN20-400
    Body Material: Steel, CF8
    Standard flanges: DIN, ANSI, JIS.
