Chemical Raw Materials (Acids and Bases)
Corrosion-Resistant Valve Solutions for Biodegradable Material Production

Shanghai Rogers Valve Co., Ltd. has partnered with COFCO Biomaterials, a subsidiary of China National Cereals, Oils and Foodstuffs Corporation (COFCO Group), to provide fluorine-lined flanged butterfly valves for a groundbreaking 30,000-ton-per-year lactide production facility. As a critical monomer for biodegradable polylactic acid (PLA), lactide production requires high-performance fluid control systems capable of withstanding harsh chemical environments.

Technical Execution
The project presented challenges due to aggressive media—including lactic acid and high-temperature byproducts—that caused failures in conventional valves, leading to leaks and operational downtime. Rogers Valve addressed these requirements through:
● Fluoroguard®-lined butterfly valves with PTFE/PFA coatings for superior chemical resistance 
● Triple-offset disc design ensuring zero leakage during thermal cycling 
● Energy-efficient, low-torque operation to minimize lifecycle costs 

Working in close collaboration with COFCO’s engineering team, Rogers Valve tailored valve specifications across synthesis, purification, and wastewater management stages. Pre-test validations confirmed performance reliability, ensuring on-schedule installation and commissioning.

Operational Impact

Over 2,000 hours of startup operations demonstrated zero leakage performance, reducing maintenance costs by 40% while enhancing process stability for PLA purity compliance. This outcome positions Rogers Valve as a strategic partner for COFCO’s expanding portfolio of bio-based material initiatives.

Strategic Advantage
By combining advanced fluoropolymer technology with deep industry expertise, Shanghai Rogers Valve supports global transitions to sustainable manufacturing. The project underscores how durable, precision-engineered solutions drive operational excellence in chemically demanding environments.
