API 609 Double Flanged Butterfly Valve
Structure:
Flanged butterfly valve is vertical disc structure, the shaft is integral metal hard seal, the seal ring of this valve is flexible graphite disc and stainless steel composite structure.
The metal sealed flanged butterfly valve is designed with a triple offset structure, utilizing the inherent CAM effect to completely eliminate all friction between the valve seat and sealing ring during the 90 degree stroke.
Rubber flexible seal butterfly valve adopts double offset structure design. Unlike the centerline flexible seal, the disc rotates approximately 20 degrees to quickly separate the sealing ring from the seat, thereby reducing friction.
Features of flange flexible seal butterfly valve:
1. Novel design structure, small overall size and light weight.
2. The disc is double offset, rapid opening and closing, lightweight and labor-saving operation.
2. No sliding friction between the disk and sealing ring, wear-resistant sealing surface, long service life, reliable sealing, easy adjustment.
Features of hard seal flange butterfly valve:
1. the disk sealing ring is multi-hard seal, with the double advantages of metal hard seal and elastic seal.
No matter low temperature or high temperature, it has excellent sealing performance.
2. the use of three-dimensional eccentric structure, the valve seat and the butterfly plate almost no friction, sealing more tightly.
3. the sealing surface of the valve body is made of surfaced stainless steel and cobalt-based hard alloy, which is wear-resistant and has a long service life.
4. 4. unique structure, flexible operation, labor-saving, convenient, not affected by the medium pressure level, reliable sealing performance.
