SEBIM high performance pilot safety valves have a track record of over 25,000 reactor years of international experience in the nuclear field.We deliver innovation and experience for critical valves in the Safety Related and Non-Safety areas of the Nuclear Power Plant.

Unparalleled Engineering.

Manufactured at Trillium Flow Technologies state-of-the-art Saint-Victoret, France facility, SEBIM nuclear safety valves are used worldwide and are manufactured and adapted to meet the specific requirements of each customer. Our product line is designed with unparalleled engineering knowledge and is renowned for its performance according to precise and rigorous design specifications. We specialize in valves for special applications in nuclear power plants, including steam and feed water isolation, and safety and decompression.

The SEBIM POSRV

The SEBIM POSRV range offers the following common features:

  • Autonomous “no flow” control system that works without an external power source
  • Optimal performance regardless of the type of fluid (steam, gas, liquid or two-phase mixtures)
  • A compact and tubeless design that adapts to all specific interfaces
  • No erosion of the sealing faces no grazing
  • High accuracy (greater than 1%)
  • Repeatability (less than 1%)
  • System insensitive to counter pressure
  • Ensured stability even when flow capacity is lower than the maximum low rate

Our products are designed with unparalleled engineering expertise and are trusted to perform to design in the most trying conditions. When it comes to nuclear, SEBIM is the choice when safety comes first.
