Technology development1
Special Coating of Disc & Metal Seat
  • Disc & Sealing surface roughness TCC coating or Stelite over ray After coating, polishing and lapping treatment surface roughness Ra 0.03~0.08
  • A Surface roughness of Disc & Seat surfaces
    • Solid TCC Coating and Stellite Overlay
    • Perf orm polishing and rapping after coating, and maintaining
Technology development2
Disc & Seat surfaces zero friction
  • Friction free of seating surfaces from before disc rotating
    - Interference is eliminated because valve disc moves in a linear before the Open/Close rotation and then performs with rotation acts.
  • ADisc & Seat surfaces zero friction
    • Solid Metal to Metal Sealing Basically. Can be used at high pressure by realizing sealing
