Overview of imported high-performance regulating butterfly valve products:
American YLOK imported high-performance regulating butterfly valve adopts double eccentric structure design. The valve shaft is double deviated from the center of the valve body structure, and combined with the arc sealing surface design of the valve plate, the valve plate is quickly separated from the sealing seat when it is opened to reduce the friction of the sealing surface. The valve plate has a good sealing performance when it is closed. The center self-positioning sealing valve seat structure design combined with the unique valve seat compensation sealing design enables the seat seal to be effectively compensated while reducing the friction when opening and closing, greatly reducing the operating force of the valve, and effectively improving the control accuracy of the butterfly valve degree. This series of butterfly valves have stable and reliable sealing performance and long service life. It is suitable for regulating and cutting off general corrosive gas and liquid medium.
