Abstract
A system for seating a head of a valve shaft that is received within a first axial bore in a primary bushing includes a second bushing having a second axial bore. The second axial bore has a second bore diameter, and is substantially concentric relative to the first axial bore. The valve shaft has a first shaft portion and a second shaft portion. The first portion has a first portion diameter, and the second portion has a second portion diameter. The first portion diameter is a predetermined amount less than the second bore diameter, whereas the second portion diameter is substantially equal to the second bore diameter. The first shaft portion is received within the second axial bore when the valve shaft is in the closed position. The second shaft portion is received within the second axial bore when the valve shaft is in the open position.
