Temp. Ratings: -196°C to +760°C Pressure Ratings:150 LB
Engineered for Extreme Low Temperatures
The Value Valves Butt Weld Butterfly Valve is a cryogenic-ready solution with Engineered for Extreme Low Temperatures, engineered specifically for the transportation and control of low-temperature and cryogenic media. Even under extremely low temperatures and harsh operating conditions, the valve consistently delivers high flow capacity, excellent sealing performance, and long service life.
Designed for Low-Temperature and Cryogenic Media
This Butt Weld Butterfly Valve is optimized for cryogenic pipelines and low-temperature process systems, making it suitable for:
- Transportation and control of low-temperature media
- Gas processing and treatment systems
- Cryogenic storage and regasification facilities
Typical media include:
- LNG (Liquefied Natural Gas)
- Nitrogen (N₂)
- Oxygen (O₂)
- Argon (Ar)
- Helium (He)
The valve maintains reliable operation under frequent cycling, high differential pressure, and extreme temperature gradients.
Cryogenic Valve Construction for Reliable Performance in Harsh Environments
Extended Bonnet Design for Stem and Packing Protection
The valve features an extended bonnet to effectively isolate the cryogenic zone from the stem packing area. This design minimizes the impact of extreme cold on sealing materials and actuating components, significantly extending service life and ensuring safe operation.
Cryogenic-Grade Materials and Proven Manufacturing
All wetted components are selected and processed according to cryogenic requirements. Materials and construction are verified to prevent brittle fracture and structural failure, ensuring reliable toughness and strength at temperatures down to –196°C.
High Flow Capacity, Low Pressure Drop, and Tight Shut-Off
The flow path and disc profile are optimized to provide high Cv (flow capacity) with low pressure drop, while maintaining tight shut-off. Even under repeated thermal cycling and vibration, the valve offers stable sealing performance and predictable operating torque.
Ideal Choice for LNG and Gas Processing Applications
Thanks to its dedicated cryogenic design, this valve is widely used in:
- LNG receiving terminals and storage tanks
- LNG regasification units and cold energy systems
- Industrial gas processing, separation, and purification plants
- Cryogenic storage, distribution, and pressure control systems
The Butt Weld Butterfly Valve enables end users to safely and efficiently transport and store cryogenic media, ensuring reliable system operation in the most demanding environments.
A Dedicated Butt Weld Butterfly Valve for Cryogenic Service
With its Engineered for Extreme Low Temperatures, high flow capacity, excellent sealing, and long service life, the Value Valves Butt Weld Butterfly Valve is a trusted solution for LNG, nitrogen, oxygen, argon, helium, and other cryogenic media.
It provides a robust, safe, and efficient flow control solution for low-temperature and cryogenic applications across the energy and gas industries.
