Vertical Pneumatic Sanitary Butterfly Valve - 316L Clamp End (FDA/GMP) | DELCO
The DELCO Vertical Pneumatic Sanitary Butterfly Valve is specialized for sterile fluid control in vertical pipelines, offering a space-saving design with zero dead legs. Manufactured from 316L / 304 Stainless Steel with a mirror-polished finish (Ra ≤ 0.8μm), it fully complies with GMP and FDA standards. Featuring a Tri-Clamp connection for rapid disassembly, this valve supports CIP/SIP cleaning, making it ideal for biopharmaceutical, vaccine production, and dairy processing lines.
Size Range:DN40-DN1200
Material:Cast Iron, WCB, SS304/316 etc.
Connection Standard:GB / ANSI /JIS /DIN
Technical Features
Designed for hygienic critical applications, this valve combines sterile compliance with vertical installation efficiency
✅Vertical Design for Space Saving & Residue Prevention：Specifically engineered for vertical pipelines, this unique structure minimizes the installation footprint compared to horizontal actuators. The vertical stem design prevents medium retention and ensures complete gravity drainage, eliminating the risk of cross-contamination in sterile batches.
✅FDA-Compliant Hygienic Surface (Ra ≤ 0.8μm)：The valve body and disc are machined from high-purity Stainless Steel 304/316L. All fluid-contact surfaces undergo mirror polishing to Ra ≤ 0.8μm, ensuring no bacteria buildup. The design is free of dead corners, fully supporting CIP (Clean-in-Place) and SIP (Sterilize-in-Place) processes.
✅Food-Grade Sealing System：Equipped with premium soft seals available in EPDM or Silicone (customizable to high-temp glue). These seals are compliant with food safety standards, providing excellent resistance to aging and sterilization cycles while ensuring a bubble-tight shutoff for high-value media like vaccines or dairy.
✅Integrated Pneumatic Automation (AT Series)：Powered by DELCO’s reliable AT Series Pneumatic Actuator (available in Single Acting or Double Acting). It provides rapid response and precise flow control. The actuator body is designed for clean environments, and standard ISO mounting allows for easy integration of position indicators and solenoid valves.
✅Quick-Clamp Connection for Easy Maintenance：The valve utilizes a standardized Clamp Connection (matching generic sanitary sizes 1/2"–4"). This allows for tool-free disassembly within seconds, significantly reducing downtime during routine inspection, cleaning, or seal replacement in high-frequency production cycles.
