Product Features
Triple eccentric butterfly valve adopts triple eccentric structure design, and the valve plate has no friction with the seat in the full travel range of opening and closing, eliminating leakage caused by valve seat wear caused by opening and closing of rotary control valve.The valve seat adopts multi-layer structure and USES the combination of metal and non-metal materials to form the sealing surface.It performs well in both high and low temperature conditions.The series butterfly valves have long service life;Excellent sealing performance, suitable for almost all gas and liquid regulation and cut-off applications in industrial process control.
1.Double /Three eccentric structure,strictly sealing ,long durable and lifetime
2.Novel design, reasonable, unique structure, light weight, quick opening and closing.
3.High pressure resistance, corrosion resistance, wear resistance, long service time, etc.
