Features & Benefits

The Series 3W Cx wafer and Series 3L Cx lug style resilient seated butterfly valve feature a vulcanized seat, a profiled disc sealing edge, and stem bearings. These features provide optimized performance and efficient automation solutions for a long cycle life without compromising bubble tight sealing.
  • 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 excpetional service life.

  • D. Stem Bushing

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

  • E. Robust Flange Sealing

    Tear-dropped shaped seat face enables tight sealing with a wide variety of industrial flanges.

  • F. Molded-in Seat

    Tightly controlled molding process produces accurate and repeatable dimensions, which leads to consistently lower torques over the valve’s lifetime.

  • G. Precision Profiled Disc Sealing Edge

    Extends the valve life by reducing seat wear.

  • H. Upper and Lower Stem Bearings

    Reduce operating torque and increase reliability in high cycle applications.

  • I. End of Line Capability

    Lug style valve allows for sealing at full rated pressure even when the downstream flange is removed.
