Valve Reassembly

1. Place the cage gasket (key 2) and cage subassembly (key 3) in the valve body (key 1).
2. Tighten the cage (key 3) hand tight plus 1/8 of a turn [For valves with rated Cv's greater than or equal to 1.0, insert
the plug guide (key 33)].
3. Place the seat plug (key 4) into the valve body (key 1).
4. Place the bonnet gasket (key 5) into the valve body (key 1). Look at the bonnet (key 6) and valve body (key 1) for
correct bonnet orientation.
5. Place the bonnet (key 6) onto the valve body (key 1) and secure with the hex nuts (key 7). For alloy valve bodies,
place the bonnet (key 6) onto the valve body (key 1), then place the bonnet flange (key 34) over the bonnet -
confirm correct orientation - then secure with the hex nuts (key 7).
DO NOT TIGHTEN AT THIS POINT.
6. Install the stem guide (key 8) and packing kit (key 9) on the plug stem (key 4) in the proper order (as shown in
figure 4).
7. Carefully press into the top of the bonnet (key 6) making sure each part is seated properly.
8. Install packing rings over the stem one at a time. Use the packing follower nut (key 11) to push each packing ring in
individually to avoid jamming.
9. With all required packing (key 9) in place, tighten the packing follower nut (key 11) until it becomes stiff.
DO NOT OVERTIGHTEN THE PACKING FOLLOWER (key 11).
10. Now tighten the hex nuts (key 7).
