Abstract
A stuffing box assembly for a valve includes a stuffing box and a packing module. The packing module carries one or more seals to engage with the stuffing box and a valve stem extending through the stuffing box. The packing module is able to be installed into, and removed from, the stuffing box as a single assembly. A valve stem can be formed with an integral ball on one end for engaging with a valve seat. The seals of the packing module create a fluid-tight seal against the valve stem and the stuffing box to inhibit fluid leakage through the stuffing box.
