摘要： A valve seat apparatus for use with fluid valves is described. An example valve seat apparatus includes a flexible seal disposed between a cage (316) and a valve body (306) such that an outer seating surface of a closure member (344) slidably coupled to the cage slidingly engages the flexible seal to prevent fluid flow through the valve body when the valve is in a closed position and an end of the closure member (344) is not driven into abutting engagement with another seating surface when the valve is in the closed position.
