DONJOY sanitary butterfly valves are designed for sterile processing, featuring high-grade stainless steel construction, polished surfaces (Ra≤0.8μm), and various connections. They comply with 3-A and FDA standards, ensuring zero fluid retention and full CIP/SIP compatibility.
Ideal for pharmaceutical, food, and beverage industries, these valves support manual, pneumatic, or electric actuation. Their leak-proof design and smooth operation minimize maintenance while enabling integration with automated cleaning systems.
Working Principle: The valve operates through a 90-degree disc rotation mechanism, which controls fluid flow by aligning or blocking the pipeline. The precision-machined disc ensures bubble-tight shut-off and minimal pressure drop during operation.
Power & Actuation: These valves support manual hand-lever operation, pneumatic actuation with cylinder drives, or electric motor control. Automated versions integrate position sensors for real-time feedback and process automation compatibility.
Operational Efficiency: Featuring quick-clamp connections and smooth surface finish, the valves enable rapid installation and efficient cleaning cycles. Their streamlined design reduces turbulence and prevents bacterial accumulation in hygienic processes.
