Three biased multi-level metals hard seal butterfly valves series,is the long life whice the our company newly develops,not divulges,the energy conservation butterfly valve.The product conforms to nation standard JB/T8527-97(metal hardly to seal reed valve),GB/T13927-J92(general valve pressure test)the standard and the valve other correlation standardsStipulations,unifies the domestic and foreign advanced technologies,uses the three dimensional eccentric principle design,The seal packing cllar uses hardly softly seals the concurrently multi-levelstructure,is suitable to the medium temperature<=65℃ metallurgy,the electric power,the petroleum chemical industry,the air,the coal gas,as well as for medium pipeline on and so on the draining water makes the adjustment current capacity and the interruption fluid,the sealing property is reliable,is the general reed valve presses,center high temperature domain extending to the center with the development.
1,The butterfly board seal packing collar for hard is soft double-decked,has the hard soft seal dual merit,regardless of in the low temperature orunder the high
Temperature operating mode,has the fine sealing property.
2,Use three eccentric structures,the valve seat and the butterfly board nearly no friction,has the pass tighter sealing property,achieved zero divulges.
3,Opens shuts the moment of force slightly the operation nimble,the vigor energy conservation,the service life is longer.
4,Thermostable,bears the high pressure,the anti-corrosive applicable scope is broad,
5,the new generation of three biased four fluorine seals reed valve concurrentfly has had three biased seals sturcture and the soft seal merit,the sealing property more reliable,the applicable scope broader,the service life is longer,
6,electrically operated,the pneumatics use the domestic and foreign famous products,performance is more reliable(may assign by user|)
