  • Butterfly valve with two-way pressure enhanced sealing
    Patent number: 4138090
    Abstract: A high-pressure butterfly valve having pressure enhanced sealing which comprises a valve body defined by a pair of interfitting body plates that are retained in assembly by bolts that also secure the valve mechanism into a flow line. The interfitting valve plates also cooperate to define a seal recess within which is received annular sealing means that provide a peripheral seal about a butterfly disc that is rotatably supported within a flow passage defined by the valve body plates. The annular sealing means also includes a pressure-responsive portion that is energized by pressure upstream of the butterfly element and which is directly responsive to pressure to urge the sealing portion thereof into sealing engagement with the periphery of the butterfly element.
    Type: Grant
