Velan Introduces Advanced Cryogenic Valve Solutions for LNG and Low-Temperature Applications
As global demand for liquefied natural gas (LNG) and low-temperature process systems continues to grow, the need for reliable cryogenic valve technology has never been greater. Velan has responded with advanced cryogenic valve solutions designed to perform in extreme low-temperature environments while maintaining sealing integrity, safety, and long-term reliability.
From LNG terminals to gas processing facilities and emerging hydrogen infrastructure, cryogenic valves play a critical role in ensuring safe and efficient operation under conditions where conventional valve designs would fail.
DESIGNED FOR EXTREME LOW-TEMPERATURE CONDITIONS
Cryogenic applications typically involve temperatures as low as -196°C, placing significant stress on valve materials and sealing components. At these temperatures, many materials become brittle, increasing the risk of failure.
Velan’s cryogenic valve designs focus on maintaining mechanical strength, toughness, and dimensional stability in these extreme environments. Careful material selection, including specialised alloys and stainless steels, ensures valves can withstand thermal contraction without compromising performance.
In these conditions, material behaviour is just as important as valve design.
EXTENDED BONNET DESIGN FOR SAFETY AND PERFORMANCE
One of the defining features of cryogenic valves is the extended bonnet. Velan incorporates this design to protect critical sealing areas and maintain safe operation.
The extended bonnet serves several key purposes:
• Keeps packing and sealing components away from extreme cold
• Reduces heat transfer from the environment into the process
• Allows safe operation and maintenance access
This design helps ensure that the valve stem packing remains at a more stable temperature, preventing leakage and improving long-term reliability. In cryogenic systems, temperature management is essential to maintaining tight shut-off.
SEALING INTEGRITY AND FUGITIVE EMISSIONS CONTROL
Achieving tight shut-off in cryogenic applications is particularly challenging due to thermal cycling and material contraction. Velan’s solutions are engineered to maintain sealing performance even as components expand and contract.
Special attention is given to:
• Seat and seal design
• Stem sealing systems
• Minimising fugitive emissions
• Consistent performance during repeated thermal cycles
In LNG and gas applications, preventing leakage is not just a performance issue — it is a safety and environmental priority. Cryogenic valves must deliver zero compromise when it comes to sealing.
APPLICATIONS IN LNG, GAS PROCESSING, AND HYDROGEN
Velan’s cryogenic valve technology is widely used across industries where low-temperature handling is essential. Key applications include:
• LNG liquefaction and regasification terminals
• Storage and transportation systems
• Industrial gas processing
• Emerging hydrogen infrastructure
As hydrogen projects expand, the demand for cryogenic-ready components is increasing. These systems require valves that can handle both low temperatures and demanding operational conditions, making precision engineering and testing critical.
TESTING, STANDARDS, AND RELIABILITY
Cryogenic valves must undergo rigorous testing to ensure performance under extreme conditions. Velan’s approach includes:
• Cryogenic testing to validate sealing performance
• Pressure and leakage testing
• Compliance with international standards
• Verification of material performance at low temperatures
These testing procedures ensure that valves can operate safely and reliably over long service periods. In high-value infrastructure projects, proven performance is essential for specification approval.
Velan’s advanced cryogenic valve solutions highlight the increasing importance of specialised valve technology in low-temperature applications. As industries expand into LNG, hydrogen, and other cryogenic processes, the demand for valves that can operate reliably under extreme conditions will continue to grow.
By combining robust material selection, extended bonnet design, and advanced sealing technology, Velan is helping to support the next generation of energy infrastructure. In these environments, cryogenic valve performance is not optional — it is fundamental to safety, efficiency, and long-term success.
