Gate Valve for Cryogenic Services – Flowbiz Exports
Controlling fluids at sub-zero temperatures requires specialized valve architecture to maintain structural integrity and prevent dangerous pressure entrapment. Flowbiz Exports Pvt. Ltd. manufactures top-tier Gate Valves for Cryogenic Services, designed to operate reliably in sub-zero environments reaching down to -196°C across Liquefied Natural Gas (LNG), liquid nitrogen, and cryogenic gas processing facilities.
What is a Cryogenic Gate Valve?
A cryogenic gate valve features an extended bonnet column that elevates the stem packing seal away from the sub-zero pipeline media. This gas column creates a thermal barrier, allowing boiled-off gas to insulate the packing gland and keeping stem seals flexible to prevent catastrophic leakage and valve stem freezing.

Key Operational Advantages
- Extended Bonnet Design: Elevates stem packing out of the cold zone, ensuring stem seal flexibility and preventing gland frost-up.
- Pressure Relief Cavity / Flexible Wedge: Features a pressure-relief hole drilled into the upstream side of the wedge to vent trapped liquid expanding in the body cavity during thermal warming.
- Stellite Hardfaced Seats: Hard-faced seating surfaces prevent galling, metal wear, and thermal binding under extreme cold cycles.
- Fire-Safe & Low Emission Packing: Flexible graphite packing and spiral-wound gaskets maintain leak-tight performance under high-pressure thermal shock.
Target Applications
- LNG Industry: Production plants, regasification terminals, LNG bunkering lines, and transport tankers.
- Industrial Gases: Air separation units (ASUs), liquid nitrogen (LN₂ ), liquid oxygen (LOX), and liquid argon handling.
- Aerospace & Chemical Processing: Liquid hydrogen ($LH_2$) fuel systems and ultra-low temperature chemical reaction loops.
