● Tight shut off seat construction

  • Disc seat‐jointless seat rings.
  • Disc seat‐exposed by tightening and contracted when bolts loosen.
  • Seat contact width‐"T", can be fine adjusted in position by tightening or loosing the retainer bolts.
  • Variation to form the most suitable contact width to meet present flow pressure without unnatural friction, but keeping perfect sealing and torque for longer lasting sealline.

※In occasion of replacing disc seat, it can be easily replaced without removing valve itself from the pipe line.
