Products Description
Need a sanitary butterfly valve that installs in seconds without tools?
Guanjiang's Sanitary Quick-Connect Butterfly Valve represents an advanced evolution in hygienic process flow control, integrating reliable quarter-turn operation with innovative quick-disconnect mechanisms. Featuring standardized sanitary clamp connections (Tri-Clamp, DIN, or ISO), it enables tool-free installation and removal — reducing maintenance downtime by up to 70%. Manufactured from premium 316L stainless steel with electropolished finishes (Ra ≤ 0.38 μm), it incorporates FDA-compliant sealing materials and maintains a smooth, crevice-free flow path for pharmaceutical and food processing applications.
Key Advantages
Tool-free installation and removal reduces maintenance time by up to 70%. Quarter-turn operation enables instantaneous flow control. Self-aligning clamp connections ensure perfect positioning.
Zero dead space construction prevents bacterial harborage. Electropolished surfaces (Ra ≤ 0.38 μm) inhibit microbial adhesion. Fully drainable design supports complete product recovery.
Bubble-tight sealing performance prevents leakage. CIP/SIP compatible for validated cleaning processes. 100% surface contact ensures consistent seal integrity.
Meets 3-A, FDA, EHEDG, and cGMP requirements. Visual position indicators prevent operational errors. Full material traceability and documentation support.
Corrosion-resistant 316L stainless steel construction withstands aggressive sanitizers and CIP chemicals.
-20°C to 150°C operating range — suitable for SIP (Steam-in-Place) sterilization.
EPDM / Silicone / FKM (Viton) / PTFE — FDA-compliant materials for various media.

Selection & Installation Guide:
Manual lever operation: For on-off applications where automation is not required.
Pneumatic actuation (double-acting): For automated on-off control — air to open and close.
Pneumatic actuation (spring-return): Fail-safe operation — spring closes (or opens) on air failure.
Electric actuation: For modulating control or when compressed air is not available.
Installation: Simply align clamp ends, insert gasket, and tighten the quick-clamp — no tools required.

Frequently Asked Questions
Q1: How does a quick-connect butterfly valve differ from a standard butterfly valve?
A: Quick-connect valves feature Tri-Clamp (quick-clamp) ends instead of flanged or lug connections. This allows tool-free installation and removal in seconds — reducing maintenance downtime by up to 70%. Standard butterfly valves typically require bolted flanges, gaskets, and torque wrenches, taking significantly longer to install or remove.
Q2: What sealing materials are available?
A: We offer EPDM (general purpose, CIP chemicals), Silicone (high purity, pharmaceutical, wide temp range), FKM (Viton) (chemical resistance, oils, high temperature), and PTFE (maximum chemical resistance). All materials are FDA-compliant for food and pharmaceutical contact.
Q3: Is the valve suitable for CIP and SIP processes?
A: Yes. The zero dead space design and electropolished surfaces (Ra ≤ 0.38 μm) 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 seat material). No disassembly is required for cleaning.
Q4: Can this valve be automated?
A: Yes. We offer pneumatic actuators (double-acting or spring-return) and electric actuators for automated control. The quick-connect design remains unchanged — the actuator mounts directly to the valve top. Pneumatic actuators provide rapid on-off cycling; electric actuators offer modulating control (4-20mA).
Q5: What documentation is provided for pharmaceutical applications?
A: For pharmaceutical applications, we provide mill certificates (EN 10204 3.1) with full material traceability, surface finish test reports (Ra measurements), seat material certificates (FDA compliance), and actuator documentation. Optional 3.1 certification for wetted parts is available upon request.
