Products Description
Need an automated sanitary valve that installs in minutes without tools?
Guanjiang's Pneumatic Quick-Install Butterfly Valve represents an advanced generation of flow control equipment that integrates pneumatic actuation with quick-connect installation technology. Combining reliable quarter-turn operation with modern quick-clamp (Tri-Clamp) connection systems, it enables rapid deployment and exceptional performance in hygienic process applications. Manufactured from 316L stainless steel with electropolished surfaces (Ra ≤ 0.38 μm), it features zero dead leg construction and supports full CIP/SIP processes — reducing installation time by up to 80% compared to traditional flanged valves.
Key Advantages
Quick-connect ends reduce installation time by up to 80%. Tool-free assembly eliminates special equipment requirements. Pre-assembled actuator-valve units ensure perfect alignment.
Electropolished surfaces (Ra ≤ 0.38 μm) prevent bacterial adhesion. Zero dead leg design supports complete drain-ability. CIP/SIP compatible for validated cleaning.
Pneumatic actuation enables precise flow modulation. Quarter-turn operation ensures rapid response. Multiple control signal options available (4-20mA, 0-10V).
Bubble-tight sealing across full pressure range. Resilient seals maintain integrity from -20°C to 150°C. Corrosion-resistant materials withstand aggressive sanitizers.
Manual override capability for emergency operation — allows valve operation even without compressed air.
Compact design saves valuable space in tight process areas. Multiple mounting orientations supported.
Double-acting / Spring-return (fail-safe) / Positioner / Limit switch / Solenoid valve — fully customizable.

Actuator Selection Guide:
Double-acting: Air pressure opens and closes — suitable for applications where fail-safe position is not critical.
Spring-return (normally closed): Spring closes valve on air failure — for safety-critical applications.
Spring-return (normally open): Spring opens valve on air failure — for cooling water, emergency venting.
Positioner (4-20mA): Modulating control for precise flow regulation.

Frequently Asked Questions
Q1: How does a quick-install butterfly valve differ from a standard butterfly valve?
A: Quick-install valves feature Tri-Clamp (quick-clamp) ends instead of flanged or lug connections. This allows tool-free installation in minutes rather than hours. They are also designed with electropolished surfaces and zero dead legs for sanitary applications. Standard butterfly valves typically require bolted flanges, gaskets, and torque wrenches.
Q2: Can this valve be used for modulating (throttling) control?
A: Yes. With the addition of a pneumatic positioner (4-20mA or 0-10V input), the valve can provide precise modulating control for flow regulation. The butterfly valve design offers good rangeability (typically 20:1) for throttling applications. Specify "with positioner" when ordering for modulating service.
Q3: What happens if compressed air fails?
A: For safety-critical applications, we recommend spring-return actuators. Upon air failure, the spring will automatically move the valve to the fail-safe position (normally closed or normally open). A manual override is also available on most actuators for emergency manual operation.
Q4: Is the valve suitable for CIP and SIP processes?
A: Yes. The zero dead leg 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.
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.
