Abstract : A butterfly valve is disclosed comprising a solid body, or casing, having a horizontal boring therein forming a passageway between the inlet and outlet ports and a vertical boring, or chamber, therein extending through said passageway. The chamber is for the containment of a cartridge having a rotatable shaft bearing a butterfly disc located at a point on the shaft where they open or close the passageway by proper rotation of the shaft. The shaft extends through the cartridge, through the cartridge support member, and outside the body. A handle is mounted on the shaft for rotating it. The shaft and cartridge are sealed by o-ring seals against passage of the fluid which is being transported by the inlet and outlet piping. (Author)
