Description
Wafer Butterfly Valve with 316 Stainless Steel Disc NBR Seat
The wafer body design is such that it can be used with most international flanges including AS2129, BS10, ANSI, DIN & JIS Standards in sizes 50mm to 300mm. The wafer style is designed for inline service and relies on a flange either side of the valve to secure in the pipeline.
