Products Details

Cryogenic Flanged Globe Valve (Cryogenic Flanged Globe Valve) is a valve specially used in cryogenic medium piping systems, with flexible switching and reliable sealing characteristics. The following is a detailed description of the low temperature flange globe valve:

Main uses:
Low temperature flanged globe valve is mainly used for low temperature medium piping system, suitable for liquid oxygen (LO2), liquid nitrogen (LN2), liquid argon (LAr), liquefied natural gas (LNG) and other gas and liquid media.

Technical parameters:

Nominal pressure: 4.0MPa
Applicable media: LO2, LN2, LAr, LNG, C2H4 and other gas, liquid
Applicable temperature: -196℃ to +80℃
Connection mode: socket welding
Medium flow: From bottom to top
Main parts materials:

Valve body, bonnet: ZGOCr18Ni9
Valve head, stem: 0Cr18Ni9
Packing: PCTFE
Product Description:
The body of the low temperature flange globe valve and the parts in contact with the medium have been specially treated at low temperature to ensure safe use in various low temperature media. The flow path of the valve is designed to enter low and high. When the hand wheel is rotated clockwise, the sealing packing of the valve stem and the flow gate are tightly sealed to realize the closing and cutting off. When the hand wheel is rotated counterclockwise, the stem rises and the medium flow opens.

Performance specifications:

Working pressure: 1.6MPa, 2.5MPa, 4.0MPa
Applicable temperature: -45℃, -101℃, -196℃
Applicable media: LNG, ethylene, propylene and other low temperature media
Materials: Valve body, valve cover material is LCB, LC3, valve disc, seat material is chrome-nickel steel + cobalt chrome-tungsten
Connection mode:
Low temperature flanged globe valves are connected by flanged connections and are available in a variety of sizes and pressure classes for different industrial applications.

Mode of operation:
The valve can be operated by hand wheel, worm wheel, gear box, pneumatic actuator, electric actuator, hydraulic actuator and many other ways.

Design and manufacturing standards:

Design and Manufacture: ANSI B16.34, API 600, BS 1873
Pressure - temperature rating: ASME B16.34
End-to-end connection: ANSI B16.10
End connection: 2"-24" ASME B16.5; 26"-42" ASME B16.47; Welded end ASME B16.25
Testing and verification: API 598, BS 6755
Through the above information, it can be seen that the low temperature flange globe valve plays an important role in the transmission and control of low temperature media, and its design and manufacturing standards are strict to ensure reliability and safety under extreme low temperature conditions.
