http://www.sinomachflange.com/valve/butterfly-valve/ Butterfly Valve supplier The fluorine-sealed butterfly valve can be applied to harsh working conditions, and can be used to cut off or adjust the flow of medium on the pipeline. Product performance: 1. Double eccentric sealing structure is adopted, which has the function of getting tighter and tighter when closing, and the sealing performance is reliable. 2. The main material of the valve body and butterfly plate is ductile iron, and the sealing material is 1Cr18Ni9Ti stainless steel paired with polytetrafluoroethylene, which is resistant to acid and alkali and has a long service life. 3. The valve body adopts a half-shaft structure, and the butterfly plate adopts a truss structure, which has high strength, large flow area, small flow resistance, and energy saving. 4. The worm gear drive is fully sealed, suitable for long-term immersion in water, and flexible in use. 5. The pipe network butterfly valve installed in the underground bedroom has a unique two-way synchronous display mechanism in the country, and the switch status of the valve can be observed from the front of the ground. 聽 Product Specification Transmission MethodConnection TypeNominal Diameter Dn (mm)Pressure Range PN (MPa)Applicable MediumApplicable Temperature 鈩?/p> Material Manual, Worm gear drive, Pneumatic, Electric, HydraulicFlange Clamp100~20000.25~2.5Water, oil, gas-30~150Ductile iron Carbon steel Stainless steel StandardGB/T12238銆丟B/T12221銆丟B/T13927銆丣B/T8527銆丟B/T17241.6銆丟B/T9115.1銆丟B/T9113.1 聽 Application Butterfly valve is a valve with a wide range of applications.
