Property Specification
ˇ¤Usage and features
The main structure of 815 & 830 series butterfly valve follows wafer and flanged three-eccentric structure,but 815 7 830L series butterlfy valve consist of body roumd with lugs and the design of single flange with bolting holes.815 7 830 series butterfly valve is widely applicable to petroleum,chemical industry,environmenttal protectijon water treatment,high building,water supplying and drain pipelines,and so on.
For the three-eccentric structure,reliable sealing it assures not to contact the seat when the disc is in open position and elimenate uneven load of the seats,extend the usage lifetime,and also assure the reliable sealing ability with high temperature sesistant,friction resistant,corrosion resistant,etc.
