Introduction
This product series is pilot-operated solenoid valves designed and qualified in accordance with ASME, RCC-M, RCC-E, IEEE 323, IEEE 344, and IEEE 382 standards. They have been successfully applied in the fuel transportation system of high-temperature gas-cooled reactor nuclear power projects. Due to their compact size, lightweight, high-pressure resistance, and reliable operation, these valves are suitable for use in nuclear power plants and nuclear chemical pipelines with nuclear-grade requirements.
Main Features
All rubber components are suitable for use in high-radiation and rapid temperature fluctuation environments.
High insulation class and protection level: The coil insulation class is H-grade and can meet application requirements under LOCA (Loss-of-Coolant Accident) environmental conditions.
High corrosion resistance: Materials in contact with the medium and surface materials are made of stainless steel, providing excellent corrosion resistance and adaptability to land, marine, and certain special environmental and medium conditions.
Suitable for applications under seismic conditions.
