10. General Notes

  1. Triple offset design achieves non-rubbing, frictionless disc rotation, preventing seat wear and torque spikes.
  2. Laminated Stainless Steel + Graphite seal ring provides resilient sealing with the thermal resilience of metal.
  3. Excellent flow regulation characteristics, making it highly suited for throttling and control loops in pipelines.
  4. Highly suited for cryogenic, high-pressure steam, refinery gases, desalination plants, and chemical networks.
