DGV resilient seated butterfly valves are widely used in various industries for both On-off and regulating service. Compared
with traditional globe & ball valve, butterfly valve is less weight and cost effective. Followed by the rapid development on
various elastomer materials, resilient seated butterfly valves are now used not only for water system but also for various
chemical industries.
