ShareShanghai Rogers Valve Co., Ltd. Enables COFCO’s 30,000 T/Year Lactide Project with Corrosion-Resistant Valve Solutions
Shanghai Rogers Valve Co., Ltd. has been selected by COFCO Biomaterials, a subsidiary of China’s COFCO Group, to supply fluorine-lined flanged butterfly valves for its pioneering 30,000-ton-per-year lactide production plant. Lactide, a cornerstone monomer for biodegradable polylactic acid (PLA), demands precision fluid control in highly corrosive environments.
Challenge
COFCO required valves to withstand aggressive media—including lactic acid and high-temperature byproducts—where traditional valves failed, causing leaks and downtime. Key criteria included corrosion resistance, compliance with ISO/ASME standards, and rapid customization.
Solution & Implementation
Rogers Valve delivered Fluoroguard®-lined butterfly valves featuring:
1. PTFE/PFA linings for unmatched chemical resistance;
2. Triple-offset disc design ensuring leak-free operation under thermal cycling;
3. Energy-efficient, low-torque operation reducing lifecycle costs.
Collaborating closely with COFCO’s team, Rogers optimized valve specs for synthesis, purification, and wastewater stages. Rigorous pre-testing validated performance, enabling on-time delivery and seamless commissioning.
Results
The valves achieved zero leakage during 2,000+ hours of startup operations, slashing maintenance costs by 40% and enhancing process stability for PLA purity compliance. This success solidified Rogers Valve as COFCO’s strategic partner for future bio-based material projects.
Conclusion
By integrating advanced fluoropolymer technology with industry-specific expertise, Shanghai Rogers Valve continues to support the global shift toward sustainable manufacturing, where durability and precision define operational success.
