Advanced Cryogenic Performance

Designed for use with extremely low temperatures (down to -196C), the GP Series Globe Valve features an extended bonnet and cryogenic-specific stem sealing, ensuring superior operational safety and isolation. Its robust construction and compliance with BS 6364 and API 602 standards make it the go-to choice for critical cryogenic applications in industrial gas and LNG sectors.

Flexible Connection and Size Options

Offered in a variety of end connection types-including flanged, butt weld, socket weld, and screwed-the valve is adaptable to multiple installation requirements. Sizes range from 15mm up to 300mm, suiting both compact and large-scale cryogenic systems. This versatility streamlines integration into new and existing piping setups for various gases.

Durable Material Selection

Constructed from high-grade stainless steel (SS 304/316), carbon steel, or brass, every GP Series Globe Valve promises longevity and resistance against low-temperature embrittlement. Body thickness adheres to ASME standards and is available in one- or two-piece cast or forged variants, ensuring optimal strength for demanding operating environments.

FAQ's of cryogenic globe valve GP:

Q: How does the GP Series Cryogenic Globe Valve ensure leak-tight operation at extremely low temperatures?

A: The GP Series utilizes an extended bonnet, rising stem with backseat arrangement, and specialized cryogenic stem sealing options (PTFE, graphite, or cryogenic grades) to maintain leak-tight service even at temperatures as low as -196C, complying with ANSI Class VI leakage standards.

Q: What end connections and pressure ratings are available for this valve series?

A: The GP Series Cryogenic Globe Valve can be supplied with flanged, butt weld, socket weld, or screwed ends, and supports pressure ratings of Class 150, 300, and 600, accommodating diverse piping systems and requirements.

Q: When should stainless steel, carbon steel, or brass material be selected for these valves?

A: Material selection should be based on the media fluency, compatibility with process fluids, and operating temperatures. Stainless steel is preferred for aggressive or ultra-cold applications; carbon steel suits less demanding cryogenic service; brass is used for specific industrial gas requirements.

Q: Where are these valves commonly installed and used?

A: Cryogenic Globe Valves from the GP Series are typically used in industrial settings dealing with cryogenic fluids-such as LNG plants, medical gas suppliers, chemical and gas distribution facilities, and other installations handling liquid oxygen, nitrogen, or argon.

Q: What is the process for installing and operating a GP Series valve?

A: Installation involves selecting the correct size and compatible end connections, ensuring alignment per ASME and API standards, and mounting the valve. Operation is manual via handwheel, but actuated options are available. Periodic maintenance checks ensure optimal sealing and performance.

Q: What benefits does the extended bonnet provide for cryogenic applications?

A: An extended bonnet isolates the valve packing and stem from extreme cold, reducing condensation and thermal shock, while ensuring reliable actuator and sealing performance at cryogenic temperatures.

Q: What testing standards and leakage classes are followed during manufacturing?

A: Each GP Series valve is tested to API 598 and BS 6364 requirements, guaranteeing high reliability and safety. Leakage class meets ANSI Class VI specifications, ensuring minimal to zero permissible leakage in cryogenic service.
