The food grade stainless steel ball-type tank bottom valve is a hygienic valve specifically designed for installation at the bottom of process tanks and vessels. Manufactured from high-quality 304 stainless steel and 316L stainless steel, this sanitary tank bottom valve ensures safe and hygienic discharge of liquids, slurries, and viscous products. Its unique ball structure provides tight shut-off with minimal dead space, preventing product buildup and contamination. The valve supports CIP (Clean-in-Place) and SIP (Sterilize-in-Place) cleaning processes, making it fully compliant with strict sanitary standards for food, beverage, dairy, and pharmaceutical applications.
