Concentric Butterfly Valve

In the well-known butterfly valve technology, its sealing form mostly adopts a
sealing structure, and the sealing material is rubber, polytetrafluoroethylene,
etc. Due to the limitation of structural characteristics, it is not suitable
for industries such as high-temperature resistance, high-pressure resistance,
corrosion resistance, and wear resistance. An existing more advanced reliable
concentric butterfly valve is a triple eccentric metal hard-sealed butterfly
valve, the valve body and the valve seat are connected components, and the
sealing surface layer of the valve seat is welded with temperature-resistant
and corrosion-resistant alloy materials. The multi-layer soft laminated sealing
ring is fixed on the butterfly valve concentric plate. Compared with the
traditional butterfly valve, our concentric butterfly valve for sale has high-
temperature resistance, is easy to operate, and has no friction when opening
and closing. When closing, the torque of the transmission mechanism increases
to compensate for the sealing, which improves the concentric flanged butterfly
valve. The advantages of sealing performance and extended service life. UTOMST,
as one of concentric butterfly valve suppliers, has its own concentric
butterfly valve factory. Contact us to get the latest concentric butterfly
valve price.
