Packing Replacement (Continued)
3 - 8” lever and nut operated valves have a friction cone (A21) and standard packing
(A9). Before installing the gland (A11), set the friction cone on top of the packing. Do not
lubricate the outside of the friction cone or the inside of the gland. See Figure 5.
9. Slide the gland (A11) down the plug shaft (A3) and over the studs (A12). If the valve has a
friction cone (A21), bring the gland nuts (A13) under the gland up finger tight.

10. Adjust gland nuts (A13).
3 - 8” L
EVER AND NUT OPERATED VALVES ONLY:
Turn gland nuts (A13) onto the studs (A12) until they touch the gland (A11).
Note: This is a preliminary adjustment, it will be necessary to adjust the gland nuts (A13) after the
valve is pressurized. See "Packing Adjustment" section.
11. Fasten the adaptor (when used) to the valve, lining up the scribe marks made during
disassembly.
12. Install the actuator as described in the Actuator Instructions.
13. If the actuator is a powered actuator, reconnect power to the actuator.
