Abstract

A system for regulating an axial biasing force applied to a stacked set of packing elements mounted within stationary equipment, comprising a packing loading assembly for sealing a process fluid within the stationary equipment and for applying the axial biasing force to the packing elements via a pressurized fluid from a pressure regulator. The packing loading assembly includes a gland element for mounting to the stationary equipment by a plurality of gland bolts, and an external actuation subsystem for coupling to at least one of the plurality of gland bolts for applying an axial actuation force directly to the gland element in response to the pressurized fluid. The gland element in response to the axial actuation force applies the axial biasing force to the packing elements.
