The SEBIM POSV type DSM 3000 is our most compact design from within the SEBIM safety valve range and offers versatility, robust design and proven reliability.
This model is suitable for all types of nuclear reactors which require high and low overpressure protection on liquid, steam, gas and steam/water mix applications with small capacity and high speed pressure transient. The SEBIM POSV type DSM 3000 was developed especially for submarines, scaled down reactors, experimental reactors, PWR, PHWR or HTGR. The piloting system, which is integrated into the main valve, operates under steam, gas, liquid or two phase flow duties.
The SEBIM POSV type GVG 3000 is designed for overpressure protection of the Nuclear Steam Supply System (NSSS) in all designs of nuclear reactor.
The SEBIM POSV GVG series was developed for overpressure protection of the Steam Generator or the Main Steam Lines of all designs of nuclear reactor. The GVG series is the tubeless design of the previous SGSV series and uses some tubing interface with piloting systems in operation since the 1990s.
The SEBIM POSV PRG 3000 is designed for overpressure protection in primary circuits of all designs of nuclear reactors, including third and fourth generations reactors.
The SEBIM POSV type PRG 3000 series is qualified for overpressure protection of the primary circuit of the third generation Pressurised Water Reactors (PWRs) (including EPR, VVER 1000 & 1200 etc.). Our PRG 3000 design is currently in operation throughout several primary loop second generation reactors (PWR, PHWR, VVER, and RBMK).
The SEBIM Tandem (POSV type Compact Tandem Safety Valves CTSV) features a unique design for redundant safe closure in the over-pressure protection of cooling circuits.
The SEBIM CTSV is the successor to the cold solution which has been in operation since the 1980s in French Pressurised Water Reactors. This Hot Solution design has operated globally since 1995 in VVER and CANDU reactors.The SEBIM CTSV fits various types of nuclear reactors which require high and low overpressure protection on liquid, steam, gas and steam/water mix applications.
