Half turn deepwater manually actuated gate valve range

  • Successfully completed the PR2 Performance Verification Test of API 6A Appendix F and API 17D 2nd Edition Section 5.1.7.
  • The stem seal is a unique Moly filled PTFE multi-ring chevron style gland set incorporating two spring energised ‘U’ cup seals.
  • Metal to Metal seals between seat to gate, seat to body, body to bonnet and backseat.
  • Wave spring behind seats provide low pressure sealing and protects the valve cavity from debris.
  • Precision needle roller bearings take up the stem thrust load, reducing operating torques to a minimum.
  • Half turn operation provides simple position indication.
