CNG LNG LPG 상부 진입 극저온 트러니언 볼 밸브

The CNG LNG LPG top entry cryogenic trunnion ball valve is specifically designed to handle extremely low temperatures and high-pressure gases in cryogenic applications like liquefied natural gas (LNG), compressed natural gas (CNG), and liquefied petroleum gas (LPG) systems. Its top entry design allows for easy maintenance and inspection of internal parts—such as seats, seals, and the trunnion-mounted ball—without removing the valve from the pipeline, which is critical in large-scale, continuously operating cryogenic systems. The trunnion support ensures stability of the ball under pressure, providing low operating torque and enhanced sealing performance. With materials and extended bonnets selected to withstand cryogenic conditions, this valve prevents cold leakage and ensures tight shutoff at temperatures as low as -196°C. Its robust construction and compliance with international cryogenic standards make it a trusted solution for safe, efficient, and long-term flow control in gas storage, transfer, and vaporization processes.
