LQH's Cryogenic Gate Valve is specifically designed to seal tightly in ultra-low temperature environments down to -196°C (-320°F), making it ideal for LNG, liquid nitrogen, and oxygen applications. Its rising stem wedge design ensures minimal pressure drop when fully open, while the extended frost-proof bonnet prevents freeze-ups. Constructed from stainless steel with graphite sealing, it maintains reliable performance in aerospace, energy, and laboratory cryogenic systems. The valve features fire-safe certification and complies with international standards, offering both bidirectional shutoff capability and long service life.
Manufactured to meet stringent international standards for cryogenic service, our gate valves undergo rigorous testing to guarantee performance in the most demanding low-temperature applications.
Available with extended bonnets to isolate packing from cryogenic temperatures, preventing stem freeze and ensuring smooth operation in ultra-cold environments.
