With temperatures as low as -196°C, UAE cryogenic valve suppliers offer specialized valves for cryogenic applications that handle liquefied gases such as LNG (Liquefied Natural Gas), liquid nitrogen, liquid oxygen, and argon. These industrial valves are designed to provide safe and dependable control of cryogenic fluids in the energy, petrochemical, industrial gas, and oil and gas industries. Cryogenic globe valves, cryogenic gate valves, cryogenic ball valves, and cryogenic check valves are common varieties. They frequently have an expanded bonnet shape to shield actuators and seals from extremely cold temperatures. To prevent brittleness, materials usually consist of 304/316 stainless steel and forged bodies; specifications for low-temperature service follow BS 6364.
Services include technical valve sizing and selection, pressure and cryogenic testing, certification (including CE and ATEX certification for hazardous areas), and post-purchase assistance for valve maintenance and repair throughout the United Arab Emirates.
Typical UAE Price Range (AED):
• Cryogenic Ball Valves (1/2" - 2"): 450 – 2,500/pc
• Cryogenic Globe Valves (1/2" - 4"): 600 – 4,000/pc
• Cryogenic Gate Valves (2" - 8"): 1,200 – 9,000/pc
• Cryogenic Check Valves (1" - 6"): 550 – 5,500/pc
Note: Prices differ according to the kind of valve, size, pressure rating (Class 150 to 900), material grade (SS304/SS316), and order volume (project/bulk supply).
CE & ATEX certification.

A cryogenic valve is specially designed for handling media at very low temperatures, like liquid nitrogen or LNG. Its unique features, such as an extended bonnet design, maintain the stem seals at a warmer temperature to prevent freezing and ensure reliable operation.
The extended bonnet moves the actuator and stem packing away from the extremely cold fluid. This prevents the packing from freezing solid, which would stop the valve from working and cause seal failure.
Stainless steel 304/316 is the most widely used material because of its exceptional toughness and resistance to brittleness at low temperatures. Materials that maintain their flexibility in cold conditions, such as PCTFE or PTFE, are frequently used for sealing in interiors.
BS 6364 is the most important international standard for low-temperature valves. Other widely used standards that address design, pressure ratings, and testing criteria include API, ASME, and ISO.
No, a typical ball valve is not appropriate. Cryogenic ball valves are specifically adapted with features including an extended stem, cold-proof seals, and often a bleed port to properly manage the expansion of trapped liquefied gas.
