Products Description
Need a hygienic, automated flow control valve for your pharmaceutical or food processing line?
Guanjiang's Sanitary Pneumatic Butterfly Valve combines quarter-turn operation with pneumatic automation — providing rapid, precise flow control for hygienic applications. The 316L stainless steel body features an electropolished finish (Ra ≤ 0.38 μm) with zero dead leg construction, preventing bacterial adhesion and product entrapment. Fully CIP/SIP compatible and meeting 3-A, FDA, and EHEDG standards, it's the ideal choice for pharmaceutical, food & beverage, and biotechnology processes.
Key Advantages
Electropolished surfaces (Ra ≤ 0.38 μm) prevent bacterial adhesion. Zero dead leg construction eliminates product entrapment areas.
Pneumatic actuation provides precise control and fast response. Low torque requirement ensures smooth, reliable operation.
Prevents leakage and contamination. Resilient seals maintain integrity across temperature variations — suitable for both pressure and vacuum applications.
Meets strict sanitary standards with full material traceability and documentation. Suitable for food, pharmaceutical, and biotech applications.
Supports automated cleaning and sterilization — ideal for sanitary processing with minimal downtime.
Corrosion-resistant 316L stainless steel with precision-machined components for long-term reliability.
Available with Tri-Clamp, DIN, or ISO sanitary ends for easy installation and maintenance.

Frequently Asked Questions
Q1: What is the surface finish requirement for sanitary applications?
A: Our sanitary butterfly valves feature an electropolished finish of Ra ≤ 0.38 μm (15 Ra). This ultra-smooth surface prevents bacterial adhesion and biofilm formation, making it suitable for pharmaceutical, biotech, and food applications requiring strict hygiene standards.
Q2: Can this valve be used for CIP and SIP processes?
A: Yes. The zero dead leg construction and electropolished surfaces make it fully CIP (Clean-in-Place) and SIP (Steam-in-Place) compatible. The valve can withstand typical CIP chemical cycles and SIP steam temperatures (up to 150°C depending on seal material) without disassembly.
Q3: What is the difference between double-acting and spring-return actuators?
A: Double-acting actuators use air pressure to both open and close — suitable for applications where fail-safe position is not critical. Spring-return actuators use air pressure to open (or close) and a spring to return to the fail-safe position upon air loss — recommended for safety-critical applications. Both are available.
Q4: What sanitary certifications does this valve meet?
A: Our sanitary pneumatic butterfly valves are designed and manufactured to meet 3-A Sanitary Standards, FDA compliance for food contact materials, and EHEDG guidelines. Full material traceability documentation and certificates are available upon request.
Q5: What connection types are available?
A: We offer Tri-Clamp (sanitary clamp), DIN, ISO, and custom connection standards. Tri-Clamp is most common for pharmaceutical and food applications due to its quick-connect design, ease of cleaning, and compliance with sanitary standards.
