Introduction
A valve designed to change the direction of fluid flow or selectively supply fluid between two lines in cryogenic fluid systems.
It is engineered for stable operation in cryogenic environments such as LNG, liquid nitrogen (LN₂), and liquid oxygen (LO₂), providing reliable switching functionality and excellent sealing performance. This enables stable flow control and supports continuous system operation.
The Cryogenic 3-Way Changeover Valve is widely applied in LNG storage and supply facilities, cryogenic gas processing systems, industrial gas plants, and marine and shipbuilding sectors. It is primarily used for safety valve isolation in C-type LNG tanks.
