The Wafer-Type Plain End Hygienic Butterfly Valve is a space-saving, high-purity valve designed to be "sandwiched" between two pipe ends. Unlike standard welded valves, the wafer body is held in place by bolts connecting two separate plain (butt-weld) flanges. This allows the central valve body to be removed for maintenance without cutting the line. Made of SS316L, it is 3A/FDA compliant, featuring a mirror-polished finish ideal for compact pharmaceutical and food skids.
