When lubricating the valve stem packing, where else should oil be applied?

When lubricating the valve stem packing, applying oil to both the valve stem and exposed threads is crucial for ensuring smooth operation and longevity of the valve. The valve stem is the component that moves up and down or rotates to open and close the valve. Adequate lubrication on the stem reduces friction, prevents wear, and ensures that the stem operates freely within the packing.

In addition, lubricating the exposed threads is essential because these threads can create additional friction and can lead to seizing if they are not properly maintained. By keeping the threads lubricated, the valve can be adjusted or serviced easily without damaging the components. This comprehensive approach to lubrication not only enhances the functionality of the valve but also protects it from wear and corrosion over time, ensuring reliable performance in the system it serves.
