Generally accepted practices can minimize the chances of improperly torqueing the gland nuts: 1. Clean and inspect the nut and bolts threads for corrosion and thread damage. The nut should be able to smoothly travel the length of the bolt. Test by finger tightening the nut on the bolt prior to installation. 2. … See more Torque, applied to the gland bolt nuts during valve packing installations and readjustment, creates an axial force on the packing gland. This axial force transfers to the packing, causing … See more The bolt torque is dependent upon packing cross section, gland bolt diameter, packing style, sealed pressure and the number of bolts. The following equation can be used to determine appropriate bolt torque. See more There are generally two methods of applying torque based on packing construction.
