Cryogenic Globe Valve

Cryogenic valves include cryogenic ball valves, cryogenic gate valves, cryogenic globe valve, cryogenic safety valves, cryogenic check valves, cryogenic butterfly valves, cryogenic needle valves, cryogenic throttle valves, and cryogenic pressure relief valves. These valves are primarily used in ethylene production, liquefied natural gas (LNG) plants, LNG/LPG storage tanks, receiving terminals and satellite stations, air separation units, petrochemical tail gas separation systems, low-temperature storage tanks and tank trucks for liquid oxygen, nitrogen, argon, and carbon dioxide, as well as pressure swing adsorption (PSA) oxygen generation systems. The transported cryogenic media-such as ethylene, liquid oxygen, liquid hydrogen, LNG, and liquefied petroleum products-are not only highly flammable and explosive but also undergo vaporization with hundreds of times volume expansion when temperatures rise.
Material Selection for LNG Valves
The material quality of LNG valves is critical. Substandard materials may lead to external or internal leakage in valve shells and sealing surfaces. Inadequate mechanical properties, strength, or stiffness in components can result in fractures, potentially causing explosions due to LNG leakage. Thus, material selection is the foremost priority in the development, design, and manufacturing of LNG valves.

1. Design: API6D, JB/T7749

2. Valve routine inspection and testing: according to API598 standard.

3. Valve low-temperature inspection and testing: According to JB/T7749.

4. Drive mode: manual, bevel gear drive and electric drive device.

5. Valve seat form: The valve seat adopts a welded structure, and the sealing surface is welded with cobalt-based hard alloy to ensure the sealing performance of the valve.

6. The gate plate adopts an elastic structure, and a pressure relief hole is designed at the pressure inlet end.

7. The valve body of the one-way sealed valve is marked with a flow direction mark.

8. The cryogenic ball valve, gate valve, stop valve, and butterfly valve adopt a long neck structure to protect the packing. 9. Ultra-low temperature ball valve standard: JB/T8861-2004

1. Valve body and valve cover: LCB (-46℃), LC3 (-101℃), CF8 (304) (-196℃)

2. Gate: Stainless steel cladding cobalt-based hard alloy 3. Valve seat: Stainless steel cladding cobalt-based hard alloy 4. Valve stem: 0Cr18Ni9

Talent formulates the low-temperature valves produced Strict manufacturing process and special equipment are used to strictly control the quality of parts processing. After special low-temperature treatment of low-temperature stainless steel flange stop valve, the rough-processed parts are placed in the cooling medium for several hours (2-6 hours) , to release stress, ensure the low temperature performance of the material, and ensure the precision machining size to prevent the valve from leaking due to deformation caused by temperature changes when working in low temperature conditions. The assembly of the valve is also different from that of ordinary valves, and the parts need to be strictly cleaned. , remove any oil stains to ensure performance.

1. Low temperature valve test device

2. Liquid nitrogen storage device

3. Low temperature treatment tank

4. Low temperature test bench to ensure the performance of the valve under low temperature working conditions

5. Others

Cryogenic Globe Valve is widely used in industries where reliable flow control and tight shut-off are required under extremely low temperature conditions, including:

LNG (Liquefied Natural Gas) Processing and Transportation
LPG (Liquefied Petroleum Gas) Systems
Cryogenic Gas Storage
Petrochemical Industries
Oil & Gas
Chemical Processing
Air Separation Units
Cold Storage Facilities

These valves are designed to provide reliable operation and safety in sub-zero environments where standard materials and designs would fail. Their extended bonnet design protects the valve's stem seals from freezing, ensuring efficient operation and long service life.
