brief introduction
This series of products are pilot solenoid valves, which are designed and identified in accordance with ASME, RCC-M, RCC-E, IEEE323, IEEE344 and IEEE382 standards, and have been successfully applied in the fuel delivery system of high temperature gas-cooled reactor nuclear power project. Because of its small size, light weight, high pressure resistance, flexible and reliable operation, the product is suitable for nuclear power plants and nuclear chemical industry pipeline systems with nuclear safety requirements.
main features
1. all rubber parts can be used under high radioactive and temperature sudden environmental conditions.
2. High insulation level and high protection level: The insulation level of coil is H level, and can meet the application of LOCA environment.
3. 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.
4. meet seismic applications.
