Their extended bonnet ensures reliable insulation and smooth operation in applications such as LNG plants and industrial cryogenic systems, where extreme temperatures are common.

Flexible Port Sizes and Pressure Ratings

With port sizes from (DJ10) to 1 (DJ40) and pressure ratings up to Class 600 (40 bar), these valves address the diverse needs of industrial, medical, and gas processing operations. Their robust stainless steel or brass construction, in compliance with international standards, ensures long-term durability and safety.

FAQs of CRYOGENIC GLOBE VALVE DJ 10 15 20 25 40 (NPT):

Q: How does the extended bonnet design benefit cryogenic applications?

A: The extended bonnet on the DJ Series Cryogenic Globe Valve protects the stem and packing from direct exposure to extremely cold media, preventing ice formation and providing safer and more reliable valve operation even at temperatures as low as -196C.

Q: What types of gases and applications are these valves suitable for?

A: These valves are ideal for controlling the flow of liquefied gases such as LNG, nitrogen, oxygen, argon, air, and helium. Typical applications include industrial cryogenic systems, gas plants, and medical or laboratory environments requiring precise, leak-proof control.

Q: When should a metal-to-metal seat be selected over PTFE?

A: A metal-to-metal seat is recommended for higher temperature or abrasive applications where maximum durability is necessary, while PTFE seats are preferred for enhanced sealing in ultra-low temperature operations or when chemical compatibility is required.

Q: Where are DJ Series Cryogenic Globe Valves typically installed?

A: These valves are commonly installed in pipelines, storage tanks, vaporizing stations, and distribution manifolds in settings such as chemical facilities, LNG terminals, and hospital gas supply systems.

Q: What process and quality standards do these valves adhere to?

A: The DJ Series valves are designed and manufactured according to BS 6364 and API 602 standards, ensuring they comply with stringent requirements for cryogenic isolation valves. Each valve undergoes hydrostatic and pneumatic testing and meets ANSI B16.104 Class VI leakage requirements.

Q: How is the valve operated, and can it be automated?

A: The CRYOGENIC GLOBE VALVE DJ Series is manually operated using a wheel or handwheel mechanism, providing precise flow control for critical cryogenic services. Automation is not standard but may be customized upon request.
