brief introduction
This series of products are step-by-step high temperature and high pressure solenoid valves. Their design and appraisal conform to ASME, RCC-M, RCC-E, RCC-P, IEEE323, IEEE344, IEEE382 standards. They are suitable for nuclear power plants and nuclear chemical industry process pipeline systems with nuclear safety requirements.
main features
1., the compensatory rigid sealing sub structure can be used under high temperature and high pressure and sudden temperature changes.
2. all rubber parts can be used under high radioactive and temperature sudden environmental conditions.
3. High insulation level and high protection level: The insulation level of coil is H, and can meet the application of LOCA environment.
4. High corrosion resistance: All materials and surface materials in contact with the medium are stainless steel, which has good corrosion resistance and can be adapted to land, sea and some special environment and medium conditions.
5. has a safe and reliable valve position display system, truthfully feedback valve position.
6. meet seismic applications.
