  • Butterfly valves having sleeve inserts
    Patent number: 8091862
    Abstract: A butterfly valve having a valve body, a butterfly shaft, a butterfly plate, and a sleeve insert is provided. The valve body is made of a first material and the sleeve insert is made of a second material. The butterfly shaft is in the valve body for rotation about a first axis. The butterfly plate is in the valve body and secured to the butterfly shaft so that rotation of the butterfly shaft causes the butterfly plate to rotate about a second axis through a travel path between a closed position and an open position. The sleeve insert is in the valve body at least in a region of the travel path between the valve body and the butterfly plate.
