Required Tools
This actuator is assembled using only SAE fasteners. To service this unit, you should have a full set of
combination wrenches, Allen wrenches, a flat tipped screwdriver, a pin punch and a dead blow
hammer.
Lubrication
The valve does not require lubrication except when it is being assembled. Refer to the actuator
instructions for actuator lubrication requirements.
Fusion/Powder Coated Valves
Valves with fusion/powder coated exterior paint require flat washers to be installed
under the flange nuts when installing the valve to the pipeline flange to prevent the
paint from cracking or chipping.
Adjusting Packing
The shaft seal consists of packing in the packing chamber of the body. The packing is contained and
compressed by the packing gland. If the packing leaks, tighten the adjustment nuts (A8) on top of the
packing gland (A9), shown in Figure 2. Tighten the nuts evenly and gently — just enough to stop the
leakage. Over-tightening will cause excessive operating forces, and will decrease the life of the
packing.
