D641F46Fluorine-lined butterfly valve overview:

D641F46Fluorine-lined butterfly valves are widely used in industries such as petrochemicals and chemicals, suitable for strong acids and alkalis, with practical temperature range:-29~150Celsius, pressure used:0-2.5MpaFlanged connection arrangement, valve body, and seat.Valve CoreIntegrated liningValveDuring operation, as long as the valve liner and the plastic-lined butterfly plate come into contact with the medium, the valve can withstand medium corrosion that may be analyzed from the fabric material, and select quadrupole.SealedArrange and fit temperature-resistant and aging-resistant materials at the sealing surfaces.SIRubber elastic pads, ensuring complete zero leakage in contact with the medium, featuring tight sealing properties, and an exceptionally long service life. 

D641F46Fluorine-lined butterfly valveFeatures: 
1.Mid-position butterfly valve features the entire butterfly plate and valve seat in360°Circumferential concentric(Midline),Features bidirectional sealing function,Pressure and flow can be freely adjusted;
2.Off-Center Butterfly ValveFor the eccentricity generated in two-dimensional directionsCamThe effect will produce sufficient sealing pressure for the sealing pair.,And as work pressure increases,Seal halves generate sufficient sealing pressure.,And as work pressure escalates,Better sealing effect.
3.Four-stage loadable elastic seal,Ensured zero leakage inside and outside the valve;
4.Adjustable ball bearingPositioning,Accurate positioning,Simple structure.
