The GG50 Body EPDM Seat Wafer Butterfly Valve is a robust industrial workhorse. Featuring a Ductile Iron (GGG50) body for high mechanical strength and an AISI 316 Stainless Steel disc for superior corrosion resistance, it is built for longevity. The EPDM seat provides a bubble-tight seal in water and steam applications. Equipped with a Gearbox, it allows for precise flow regulation and easy manual operation on larger sizes, meeting both PN10 and PN16 standards.
