Valbart designed the Subsea Trunnion-Mounted Ball Valves for total reliability against internal and external leaks. The design of this quarter-turn ball valve is compatible with hydraulic actuators, ROV operated gear boxes and electrical and hydraulic umbilical systems.


  • Metal-to-metal seats for non-clean service utilizing tungsten carbide coating with ball and seat lapped. 
  • Elastomeric or lip seals prevent internal leakage. 
  • Seal surfaces are manufactured from corrosion resistant alloys, CRA, or CRA overlay to prevent corrosion. 
  • Duplex, Super-Duplex and nickel alloys (635 and 718) are used to prevent sulphide/ chlorine stress corrosion cracking. 
  • Valbart subsea valve designs are tested and validated in a hyperbaric chamber to ensure compliance with safety and functionality requirements. 
  • Certification to API 6D SS by a third party.
  • Self-relieving seats in combination with double piston effect seats provide two ball and seat seals.
