Abstract
A means for adjusting the relative positioning of a valve closure element with respect to a valve seat is formed by a hub on the closure element having a valve stem receiving bore and at least two generally opposed threaded passages intersecting the bore. Threaded members are received in each bore to engage the valve stem from generally opposite sides thereof. Movement of the threaded members adjusts the relative positioning of the closure element with respect to the valve seat and valve stems while securing the closure element to the latter.
