  • Ball valve having one-piece machined seat member
    Patent number: 5595206
    Abstract: A ball valve having a one-piece seat member is disclosed. The one-piece seat member is cylindrically shaped to engage a valve chamber within the valve body, and includes an internal cavity for receiving a ball member, a first axial opening for receiving an operating stem engaged to the ball member, and first and second radial openings that align with inlet and outlet passages in the valve body. The one-piece seat member can be machined from such materials as polytetrafluoroethylene, ultra-high molecular weight polyethylene, fluorinated ethylene propylene, or perfluoroalkoxy. To make the ball valve, the one-piece seat member is formed with the internal cavity, the first axial opening, a second axial opening opposite the first axial opening, and the first and second radial openings, and is caused to be in a deformable state.
