The API 6D Stainless Steel Top Entry Cryogenic Ball Valve is engineered for extreme low-temperature services like LNG and liquid nitrogen. Its top-entry design allows for critical in-line maintenance without disturbing the insulation cold box. Featuring an extended bonnet to protect the stem packing from freezing, it utilizes specialized lip seals and cryogenic treatment of components to ensure bubble-tight shut-off and operational integrity at temperatures as low as -196℃
