Features & Benefits

2 Cx Line
  • A. Digital Tag

    Each valve is uniquely and easily identifiable by simply scanning the QR Code on the product identification tag in accordance to IEC 61406.

  • B. Electrostatic discharge through antistatic design

    Electrostatic discharge through antistatic design (Ground washer and Top flange drilling).

  • C. Stem Design

    The high-strength stem design combine blowout-proof functionality for safe operation and exceptional service life.

  • D. Stem Bushing

    Non-corrosive, heavy duty acetal bushing absorbs actuator side thrust.

  • E. Bearings

    PTFE impregnated steel bearings provided for the precision alignment of the upper and lower stem.

  • F. Stem Seal System

    The live-loaded packing design features a primary and secondary sealing principle to comply with the most stringent fugitive emission requirements.

  • G. Seat Energizer

    A resilient seat energizer extends completely around the seat, including the disc hub providing uniform force sufficient for zero-leakage.

  • H. Disc

    The encapsulated disc has 3 mm minimum thickness of virgin-PTFE.
