BX Type Cryogenic Globe Valve
Specially Designed for Oxygen & Cryogenic Service | API 602 Compliant
The BX Type Cryogenic Globe Valve is specially engineered for handling cryogenic liquids and gases in demanding industrial applications. Designed with an extended bonnet structure, these valves effectively isolate the stem packing from the extremely low-temperature media, ensuring reliable sealing performance and preventing cryogenic leakage.
These valves are specifically designed and tested for Oxygen service, meeting the stringent requirements of medical and industrial oxygen applications. The extended stem design moves the packing assembly away from the cold zone, maintaining proper packing compression and preventing ice formation that can cause stem leakage or binding.
The BX type end connections utilize orbital welding technology for leak-tight, permanent connections that are essential in cryogenic service where even minute leaks can cause significant safety concerns or product loss. The precision-machined components and high-quality materials ensure reliable performance from -196°C (LN2, LOX, LAR) to +80°C.
