ABSTRACT:
A plunger-style valve assembly for use in a launder system of a machine for casting parts made from molten aluminum or other metal comprises a valve body having a longitudinally-extending inlet passageway and a longitudinally-extending outlet passageway which communicate with one another through a valve port centered about a vertical axis. A raised circular valve seat defines the valve port, and a vertically-movable valve element is aligned with the valve port and the valve seat. The valve element has a resilient, heat-resistant sealing member secured to the lower end thereof. The valve element can be raised or lowered so that the resilient sealing member moves into and out of engagement with the raised valve seat, thereby controlling the flow of molten aluminum from the valve body inlet passageway to the valve body outlet passageway through the valve port.
