特点和优势

4 Cx
  • A. Travel Stop

    Integrated into the top flange allows for an uninterrupted bore optimizing the flow path and reduces potential turbulence. The robust travel stop outperforms pinned designs as it offers increased shear area to withstand higher torque loads.

  • B. Stem Design

    高强度的阀杆设计结合了防吹出功能,可实现安全操作和卓越的使用寿命。

  • C. Stem Packing

    Fully-adjustable, live-loaded and field-replaceable stem packing is certified to international fugitive emission standards.

  • D. Environmental Protection

    O-Ring seals in the top flange and travel stop prevent any external contaminants from entering the valve packing area.

  • E. Seat Design

    The energized resilient seat provides bidirectional zero leakage sealing, is self-adjustable and isolated from the line media.

  • F. Pressure Assisted Sealing

    Enables optimal bidirectional sealing performance for low and high pressures.

  • G. Disc Design

    The double offset stem and disc design reduces seat wear, lower torque and ensures extended service life.

  • H. Full-faced Seat Retainer

    Uninterrupted design provides a high integrity sealing surface with available face-to-face options between mating flanges.

  • I. Stem Bearings

    Top and bottom bearings securely support the stem, provide excellent corrosion resistance and minimizes deflection.
