Multi-turn manual gate valve

  • Successfully completed the PR2 Performance Verification Test of API 6A Appendix F and API 17D 2nd Edition. Testing included a 1200 cycle endurance test at full differential design pressure.
  • Dual stem seal arrangement. The primary gland is a unique Moly filled PTFE multi-ring chevron style gland incorporating two spring energised ‘U’ cup seals. The secondary gland is a spring energised, Moly filled ‘U’ cup seal. Both seals were tested independently during qualification.
  • Stem has fully functional Metal-to-Metal back seat when valve is in the fully closed position.
  • Metal-to-Metal seal between Seat to Gate, Seat to Body and Body to Bonnet.
  • By design, the drive train failure point is external of valve.
  • Position indication system provides anchorage for indicator plate or for push-pull type indication system.
  • Drive train safety factor when compared to Nominal operating torque is well in excess of 5 to 1.
  • Unique sprung non-elastomeric seal behind seat provides low pressure sealing and protects the valve cavity from debris.
  • Slab Gate design offers uninterrupted flow passage through valve bore.
  • Standard material certification for pressure retaining and controlling parts are to API 6A PSL3 and BS EN 10204 3.1 (3.2 option available).
