Powder Butterfly Valve
The Sanitary Powder Butterfly Valve is specifically engineered for handling dry bulk powders, granules, and particulate solids in hygienic processing environments. Its design features an inflatable or elastomeric seat that provides a dust-tight seal when closed, preventing powder leakage and cross-contamination between process stages. The full-bore disc minimizes product retention and bridging during powder transfer.
