Triple Eccentric Butterfly ValveMain Features:For the structure of the triple-eccentricity seal butterfly valve, when the valve is under the complete open state, its butterfly plate sealing face will break away from the valve seat sealing face completely; when it is opened from 0 to 90°, the butterfly plate sealing face will break away from the valve seat sealing face upon opening; when it is closed from 90° to 0°, and only upon closing, the butterfly plate sealing face can contact and press onto the valve seat sealing face tightly.Main Parameter SpecificationDesign and Manufacture：API 609,GB/T 12238Face to Face Dimension：API609,ISO5752,ASME B16.10,GB/T 12221Flange Connection Dimension：ASME B16.5,ASME B16.47,GB/T 9113,JB/T 79Test and Inspection：API 598,JB/T 9092,GB/T 13927Pressure Temperature Rating：API 609,ASME B16.34,GB/T 12224Product RangeBody material:Cast Steel,Stainless Steel,MonelNominal diameter:2"～120"（DN50~DN3000）End Connection: Double Flange,Wafer,Lug,etcPressure range: Class150 ~ 600（PN16~PN100）Working temperature:-46℃ ~ +550℃Operation : Handle, Gear, Electric actuator, etc
