Precision Engineering for Extreme ConditionsDesigned to perform reliably under demanding cryogenic conditions, the DJ GA GK globe valve supports operations between -196C and +80C. The extended bonnet ensures safe operation by maintaining gland packing above freezing, reducing risk of icing and enhancing long-term performance even in applications involving LNG and liquefied gases.
Versatile Connections and Superior SealingAvailable with flanged, butt weld, or socket weld ends, this globe valve integrates smoothly into various piping systems. Choose between PTFE or metal seats, with Class VI/bubble tight sealing for exceptional leak prevention. Its full port and low noise level promote efficient, quiet flow management across size ranges DN15 to DN300.
FAQ's of CRYOGENIC GLOBE VALVE DJ GA GK:
Q: How does the extended bonnet benefit cryogenic service applications?
A: The extended bonnet design provides thermal insulation by distancing gland packing from the cold process fluid, thus preventing freezing and ensuring reliable, long-term operation in low-temperature environments such as LNG, liquid oxygen, or nitrogen systems.
Q: What standards does the CRYOGENIC GLOBE VALVE DJ GA GK adhere to?
A: The valve is manufactured in compliance with BS 6364, API 602, and ASME B16.34 design standards and undergoes rigorous testing as per API 598, which ensures performance, durability, and leakage integrity for critical cryogenic services.
Q: When should I choose PTFE versus metal seated options for this valve?
A: PTFE seats are best suited for applications seeking superior sealing performance and resistance to aggressive chemicals, while metal seats are recommended for higher temperatures or abrasive conditions where increased durability is required.
Q: Where is the CRYOGENIC GLOBE VALVE typically installed?
A: This valve is commonly installed in cryogenic processing plants, LNG facilities, storage terminals, and industries handling liquid oxygen, hydrogen, or nitrogen, where maintaining tight shutoff at very low temperatures is essential.
Q: What is the process for customizing the valve for specific capacity or size requirements?
A: Customization depends on project specifications; you can request the required size (from 1/2" to 12"/DN15 to DN300) and material (stainless, carbon, or alloy steel). Capacity and connection types are tailored based on operating conditions, with technical consultation provided by the manufacturer or supplier.
Q: How is the globe valve operated, and what actuation options are available?
A: Standard operation uses a manual handwheel, ensuring straightforward on-site control. For automation, actuated options can be requested, enabling integration into remote or automated process systems.
