VALVE SEAT APPARATUS FOR USE WITH FLUID VALVES |
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 and a valve body such that an outer seating surface of a closure member 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 is not driven into abutting engagement with another seating surface when the valve is in the closed position.
