Nuclear grade forged steel T-shaped corrugated pipe globe valve
2025-10-18
The basic design function of nuclear grade forged steel T-shaped corrugated pipe globe valve is to cut off or connect the medium flow in the pipeline under required working 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 the operational requirements of normal and accident conditions.
