When ultra low profile is required we offer the SB Sanitary Butterfly Valve. Compliant with the USDA 3A requirements for manual cleaned butterfly valve for handling dry powders. The valve dismantles by hand in minutes for quick inspection and cleaning. Manufactured in the US from 316L Stainless Steel and FDA Silicone seals the valve is offered in #4 satin or #7 mirror polish with manual or air operators. Standard and engineered options such as weld necks and Tri-clamps are also offered. Many sizes are stocked or are available with short lead times.
