Product Details of Pneumatic Fluorine Lined Butterfly Valve D641F:
Introduction of Pneumatic Fluorine Lined Butterfly Valve D641F:
Core Structural Advantages
The valve body adopts a split-type design for easy maintenance and assembly.
Seal integrity at both ends of the valve shaft is ensured by fluororubber gaskets, which form a tight seal on the rotating interface between the valve disc and seat.
A key benefit of this design: the valve shaft is completely isolated from the fluid medium inside the cavity, preventing corrosion and wear and further extending service life.
