Cryogenic Extended Stem Globe Valve
The Cryogenic Extended Stem Globe Valve is a specialized flow control device engineered for reliable operation in extremely low-temperature environments. Featuring an extended stem design, it prevents the low temperature from transferring to the valve’s operating mechanism, ensuring safe and convenient manual or automated control.
This cryogenic extended stem globe valve is manufactured in accordance with stringent international and industry standards to guarantee quality and performance:
Design and Dimensional Standards: API 600, BS 1873, DIN 3356
Pressure Testing Standards: API 598, EN 12266-1
Material Standards: ASTM, ASME, and other relevant specifications for cryogenic-resistant materials
Quality Management: Produced under an ISO 9001-certified quality management system
Material Specifications
Key components are made from materials with excellent cryogenic resistance and mechanical properties:
Body and Bonnet: Stainless steel (e.g., 304, 316, 316L) or other cryogenic alloys
Disc: Stainless steel (304, 316) with hardfacing or specialized cryogenic coatings
Stem: Stainless steel (316, 416) or alloy steel with high strength and corrosion resistance
Seat Ring: Stainless steel with compatible sealing materials (e.g., PTFE, RPTFE, or metal-to-metal sealing for ultra-low temperatures)
Gaskets and Seals: Materials suitable for cryogenic service, such as flexible graphite, stainless steel spiral wound gaskets, or cryogenic-grade elastomers
