Features & Benefits

Integral ISO 5211 Mounting Pad

  • For Ease of Actuation

V-Segment Ball

  • Gives a combination of precise control and high Cv
  • V-Notch in Segment – Provides a shearing function for superior performance in slurries and viscous media, powder and particulate media, and fibrous media

Swappable Seats & Easy-To-Remove Cap

  • For ease of maintenance

Articulating Gland Flange

  • The spherical gland flange and packing follower allows for equal distribution of packing and is live loaded eliminating the need for routine packing adjustments.

Low-E Stem Packing

  • Stem Packing is designed and tested for long-term reliable low fugitive emissions performance

1-PC Body Design

  • Eliminates body flange leak path
