Bolt Torques for Die-Formed Graphite Sets
Bore Diameter (inches)
Notes: 1. This table yields ft.-lb. torque values corresponding to a 3,800 psi
gland load. This is not a suitable gland load for
all
styles of packing.

Stem Diameter (inches)
2. The values in this table are given for a valve with
two gland studs
.
The values are not valid for valves with screw type packing nuts, or for valves with more than two gland studs.
3. These torque values are valid only if gland studs are in
good condi-
tion and well-lubricated.
Torque in ft-lbs per inch of bolt diameter To estimate stud torque required for 3,800 psi gland load,
multiply gland stud diameter by the number in the table cor- responding to the correct stem and bore diameters.
