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).

For handling media at very low temperatures, like liquid nitrogen or LNG, a cryogenic valve is made especially. To prevent freezing and guarantee dependable operation, its unique characteristics, such as an extended bonnet design, maintain the stem seals at a warmer temperature.
The actuator and stem packing are moved away from the extremely cold fluid by the expanded bonnet. By doing this, the packing is kept from freezing solid, which would prohibit the valve from working and result in seal failure.
Because of its exceptional toughness and resistance to brittleness at low temperatures, stainless steel 304/316 is the most widely used material. Materials that maintain their flexibility in cold conditions, such as PCTFE or PTFE, are frequently used for sealing in interiors.
For low-temperature valves in particular, BS 6364 is the most important international standard. Other widely used standards that address design, pressure ratings, and testing criteria are API, ASME, and ISO.
No, a typical ball valve isn't appropriate. To properly manage the expansion of trapped liquefied gas, cryogenic ball valves are particularly adapted with characteristics including an enlarged stem, cold-proof seals, and frequently a "bleed" port.
