Features and benefits
- Long cycle life bellows (3000 cycles) in Gr. 321 (stainless) or Inconel. Designed and successfully tested in high pressure/temperature conditions.
- Two-part bellows.
- Two secondary stem seals: a) Backseat in open position; b) Graphite packing.
- Low torque due to: a) Non-rotating stem prevents torsion of bellows; b) Stem nut thrust bearings; c) Central lubrication.
