As a process engineer, I've seen firsthand the unique challenges faced by pharmaceutical and biopharma engineers maintaining sterility, ensuring validation, and achieving cleanability in fluid-handling systems. Our Flow-Control Valves product line is designed to address these pain points head-on, providing reliable and versatile components for high-purity applications.
Material Selection for Compliance and Performance
At KOSA Valve, we prioritize 316L stainless steel for its excellent corrosion resistance and biocompatibility, making it ideal for sanitary and industrial applications. Our valves meet stringent standards such as ASME BPE 2019 and 3-A Sanitary Standard 2022. We also offer PEEK and PTFE options for specific applications requiring even lower extractables. Validation is simplified with our comprehensive documentation package, including Certificates of Analysis (CoA) and Material Traceability Records (MTRs).
Design Features for Enhanced Cleanability
Cleanability is crucial for preventing contamination and ensuring product integrity. Our valves feature a polished electropolished finish to a 20Ra or better, which minimizes surface roughness and reduces the risk of bacterial adhesion. Additionally, our designs incorporate sanitary fittings with crevice-free surfaces, ensuring easy cleaning and sterilization. We also offer CIP/SIP capabilities, allowing for efficient and effective cleaning and sterilization processes.
Flow Control and Precision
Precise flow control is essential for maintaining process consistency and product quality. Our valves offer tight shut-off capabilities, with a maximum leak rate of 0.2 µm absolute-rated, ensuring minimal product loss and contamination. We also provide a range of actuation options, including pneumatic, electric, and manual, to suit various process requirements. Our valves are designed to handle a wide range of flow rates and pressures, providing flexibility for different applications.
Extractable Validation and Regulatory Compliance
Extractable validation is a critical aspect of ensuring product safety and regulatory compliance. Our valves are designed with materials that have been extensively tested for extractables and leachables, with results showing <1 ppb extractables under typical operating conditions. We provide detailed extractable profiles and compliance documentation to support your validation efforts. Our valves meet FDA 21 CFR and cGMP requirements, ensuring they are suitable for use in pharmaceutical and biopharma applications.
Real-World Application: A CDMO's Challenge
A leading contract development and manufacturing organization (CDMO) faced issues with valve contamination leading to batch failures. We replaced their existing valves with our Flow-Control Valves, featuring polished electropolished surfaces and crevice-free designs. The result was a significant reduction in contamination incidents, with >99.9% recovery rates and improved batch consistency.
| Valve Type | Material | Maximum Leak Rate |
|---|---|---|
| Sanitary Control Valve | 316L Stainless Steel | 0.2 µm absolute-rated |
| Industrial Control Valve | PEEK | 0.2 µm absolute-rated |
