Since 1962 SEGAULT manufactures all nuclear steam supply system (NSSS) solenoid valves of the French nuclear sub-marines and the French nuclear aircraft carrier Charles de Gaulle. Company’s experience in navy applications has allowed to develop a large range of solenoid valves for civil nuclear power plants. The solenoid valves have the following advantages comparing to electrically motorized valves:
- Reduced weight and overall dimensions
- Seismic resistance with no supporting
- High cycling (100 000 cycles)
- Quick opening or closing (less than one second)
The valves EDF qualified and are manufactured according to RCC-M or ASME III standards. All the valves comply with ESPN regulation.
The design of SEGAULT solenoid valves emphasizes the simplicity, minimum of moving parts and maximum resistance to contamination.
Balanced disc authorizes function of the valve under various conditions of differential pressure, reduces the size and weight of the coil, thus bringing the center of gravity closer to the pipe line.
Cycling under pressure, irradiation, earthquake, LOCA, K1, K2 and K3 qualification
More than 50 years of experience in various applications such as « pressurize spray » and operations on hydrogenation and primary and secondary systems of PWR.
