2025-08-18

The nuclear grade forged steel parallel double gate valve is used to cut off or connect the medium flow in the pipeline of million kilowatt and large pressurized water reactor nuclear power plant systems under required operating conditions. Allow the medium to flow when the valve is opened; When the valve is closed, it should be ensured to be cut off. The valve can only be in the fully open or fully closed position. The prototype has passed comprehensive identification tests such as cold and hot life, cold and hot alternation, cold and hot cycle, fluid blockage, vibration aging, earthquake, and end loading, and can meet various functional requirements under operating conditions.
