ABSTRACT:
A valve assembly includes a seat and a valve member. The valve member is pivotally connected to and engageable with the seat to close a flow aperture. The valve member is resiliently yieldably urged into sealing engagement with the valve seat. To open the flow aperture, a portion of the valve member adjacent the pivotal connection to the seat is initially lifted from the seat, and then the valve member is rotated relative to the pivotal connection.
