Features:

Cryogenic Treatment:
- All valve parts operating at temperatures below -100°C undergo cryogenic treatment according to relevant regulations. This process prevents low-temperature brittleness and volume changes due to material phase changes at low temperatures.
Long Neck Structure:
- The long neck design ensures the packing work temperature remains above 0°C. This prevents the packing from losing its sealing performance or failing due to low working temperatures. Additionally, it allows for easy insulation wrapping to prevent cold energy loss.
Floating Ball Valve Design:
- The floating ball valve features an inlet pressure relief outlet seal design. This effectively prevents abnormal pressure rises in the middle cavity caused by temperature fluctuations, ensuring the safe operation of the valve and pipeline.
