شیر توپی سه تکه کرایوژنیک CNG LNG LPG

The CNG LNG LPG 3-piece cryogenic trunnion ball valve is specifically designed for ultra-low temperature services where gases like compressed natural gas (CNG), liquefied natural gas (LNG), and liquefied petroleum gas (LPG) are stored and transported. This valve uses extended bonnets to keep stem seals away from cryogenic temperatures, ensuring safe and leak-free operation. The trunnion-mounted ball provides consistent sealing and reduced torque even under extreme pressure-temperature conditions, while the 3-piece body design allows for convenient in-line maintenance without disrupting the entire pipeline. Materials are carefully selected to maintain toughness and sealing integrity at cryogenic temperatures, preventing embrittlement and leakage. Its tight shut-off capability and automation compatibility make it ideal for gas processing, LNG terminals, and cryogenic tank farms. Engineered to meet industry standards for cryogenic safety and reliability, this valve plays a key role in ensuring secure, efficient flow control in low-temperature gas handling systems.
