Looks like a repop valve to me. That looks like a black "o" ring on the stem, hard to see in the picture. The rubber "o" ring acts as the seal on the stem, and takes the place of the packing. Lapping the taper to the seat can be done with toothpaste. If it is not scored, and does not leak it probably does not need to be lapped, just lubricated. Put some oil on it, work it back and forth, and reassemble.
