ABSTRACT:
The check valve includes a disc-shaped closure member mounted to the valve body for sealing engagement with an annular seat in the valve body. A stem is rotatably mounted to the valve body so that the closure member can swing into and out of engagement with the annular seat. The stem extends outwardly of the valve body and may be positioned on either side of the valve body so that a biasing or cushioning mechanism attached thereto may be positioned on either side of the valve body. An adjustment mechanism is provided for axially moving the stem with respect to the valve body, thereby laterally adjusting the position of the closure member with respect to the seat on the valve body to ensure reliable sealing engagement with the seat.
