Centerline Seal Butterfly Valve

With the disc seal center of butterfly valve and rotation center of stem overlapped,sealing load Will be produced between the sealing faces of seat and disc under certainmagnitude of interference. Thus to ensure effective seal of valve. Lined with rubber on body.This structure is applicable for me-dium and small-bore butterfly valves. Due to thedeformation under extrusion.during the process of opening and closing, disc is alwaysunder extrusion.So. the upper and lower valve shafts are seriously extruded, whichcan be bad to the service life of valve. And. the open-close moment of valve is rela-tively high. The defect is that disc and seat are always under extrusion, scra- tch, highresistance andserious adrasion. To overcome extrusion and scratch and to ensuregood seal, seat basically uses rubber or PTFE,or other elastic materials. However,temperature can be a problem. This is why butterfly valves are ,conventionally, notresistant to high temperature.
