A revolutionary concept in the realm of surface-controlled subsurface safety valves

Unlike other tubing-retrievable safety valves (TRSVs), the DepthStar TRSV functions completely independent of well pressure, enabling operation at consistently low hydraulic pressures, and making it an ideal solution for deepwater, ultra-deepwater, high-pressure/high-temperature (HP/HT), and gas storage applications. 

The DepthStar TRSV incorporates a unique magnetic coupler that allows for positioning the hydraulic actuator out of the tubing wellbore, completely isolated from well fluids and pressure, providing 100% metal-to-metal sealing with no moving seals exposed to the well environment.

  • No moving seals exposed to the tubing wellbore
  • 100% metal-to-metal sealing within the tubing wellbore
  • 100% isolation of hydraulic actuator piston from wellbore
  • Less than 5,000-psi maximum valve opening capability
  • Minimized number of body connections
  • Proven metal-to-metal, non-elastomer hydraulic actuator
  • Isolated flow tube


A complete deepwater solution

Industry's first TRSV with magnetic coupling enables safe operation at lower pressures, enhancing overall reliability and expanding opportunities.
