CXF Series

The CXF Series is a cryogenic floating ball valve designed for use in extreme temperatures as low as -196ºC, making it ideal for LNG, LPG, and other applications. It features an advanced unidirectional design with an upstream relief hole to release overpressure safely. The valve is equipped with a rib and groove, fool-proof system to ensure proper installation and operation of the safety feature, and an expansion chamber to create a barrier between the liquefied gas and the packing, enhancing the sealing system’s performance. The CXF Series is available with welding connections, making it the perfect solution for compact and permanent systems that require high reliability and safety.
