Vanessa Triple Offset Design

  • The purpose of the first offset is to have a continuous path
  • The second offset allows the displacement of the seal from the seat during the 90o opening
  • The third offset completely eliminates rubbing - the key contributor to the zero leakage performance of the valve
Reliable and Robust Zero Leakage Seating

Reliable and Robust Zero Leakage Seating

  • Vanessa disc is not the sealing element, only the carrier of the sealing ring
  • Metal-to-metal, torqued seating
  • Vanessa exclusively uses Stellite grade 21 on seats to achieve higher resistance to galling, abrasion, erosion, and corrosion
  • All metal construction makes Vanessa inherently fire-resistant
  • Non-rubbing 90o rotation means lower and consistent running torque
