TECVAL foto1831478513382

TECVAL VB-65 trunnion ball valves are designed to work with liquids under either high pressure or moderate vacuum service. Due to their trunnion solid design, these valves withstand extreme service conditions where the strongest features are required. To be used in numerous applications, they are manufactured in several sizes, connections and alloys.


  • Trunnion Ball.
  • Assembled three screwed pieces through 16 studs to allow a full disassembling on the spot.
  • Full Bore (FB) or Reduced Bore (RB).
  • Smooth operating.
  • Easy cleaning and maintenance.
  • No ejectable stem design.
  • Anti-leak stem with double o-ring seal.
  • 100% tested.


  • Automation through electrical actuator.
  • Automation through pneumatic actuator.
  • Prepared for a quick automation (ISO 5211).
  • VIC Grooved end connections.
  • Handle safety lockout.
  • O-ring seals available in several materials.
