Sanitary Pneumatic Mixproof Butterfly Valve, SS316L Tri-Clamp, Anti-Mixing Double Seal Hygienic Valve

This pneumatic mixproof butterfly valve is specially engineered for hygienic pipelines where two different fluids must be isolated reliably. It adopts a double-seat structure with an intermediate leakage chamber. If the inner seal fails, the medium will drain through the leak port instead of mixing two fluids, effectively avoiding cross-contamination. Fitted with a pneumatic actuator, it realizes automatic on-off or remote control. Available in SS304 and SS316L stainless steel with hygienic mirror polishing. Connection types include tri-clamp, welded and threaded. It is CIP and SIP compatible, widely used in dairy, juice, beer, food processing and biopharmaceutical production lines.
