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
