Figure 8

 – Cover Removal

 

Remove the spring(s) from the valve stem.

 

 

Figure 9

 – Cover Spring Removal

 

Remove the stem assembly from the valve body. On the underside of the stem, note 

that the stem may have a flat machined surface. This flat surface is dependent on 

valve size. Some valve sizes have a nut where this flat would be (Figures 10 and 11). 

Secure this flat surface or the lower stem nut in a vice as shown in Figure 12.
