Wafer Butterfly Valve
The Sanitary Wafer Butterfly Valve is a slim-profile, centerline design that fits between two pipe flanges and is held in place by flange bolts passing through the valve body. Its wafer-style body minimizes face-to-face dimensions and installation space requirements. The design is cost-effective and suitable for larger diameter pipelines in sanitary applications where space is limited.
