Abstract

A two-member valve plug comprises a lower plug member 23 and an upper plug member 22 which are in a generally axially spaced relation on the valve stem. Packing 35 is held in a snug-fitting condition between the lower and upper plug members by an axially resilient member 41 which acts between one end of the valve stem and the valve plug to urge the lower and upper plug members together. When the two-member valve plug closes a fluid passage, a force is transmitted by the valve stem directly through the upper plug member to the packing to form a leak-tight seal for the valve plug. The stem force is also transmitted through the packing and lower plug member to generate a seating force between the valve plug and a seat 17.
