Abstract
A valve having a valve packing removal device attached thereto is disclosed. The valve may include a valve plug reciprocally disposed within the valve housing and connected to a sliding stem. The packing may be provided about the valve stem to ensure or minimize leakage of regulated fluid from the valve. A sleeve may have a diameter less than a bore in which the packing is disposed and may be connected to the valve stem such that when the valve stem is sufficiently pulled from the valve, the sleeve engages the packing and pulls the packing from the valve.
