Features

  • True bi-directional, zero leakage performance for severe services
  • Patented gate edge seal system eliminates leakage through top of valve
  • Heavy cross-section, precision-molded elastomer seat increases sealing surface area to maintain zero-leakage performance for more cycles
  • Repairable asset with spare parts able to be replaced with standard tools
  • Full round port and seat design reduce pressure drop across valve to extend service life in abrasive applications
  • Integral inlet & outlet hardened wear rings minimize wear to valve body and extend service life of the asset
  • Simplify maintenance with dynamically self-adjusting gate edge seal system
