Function

75B0018X012 is packing box component manufactured by Fisher. It contains packing rings and provides radial compression for valve stem sealing. It restricts fugitive emission leakage along valve stem. It maintains stem alignment and reduces packing wear during valve stroke movement. It is key spare part for valve stem sealing overhaul.

Installation

Follow lockout/tagout safety procedure before installation. Isolate pipeline and release process pressure. Disassemble valve bonnet, replace old packing box component. Install packing rings in sequence and check stem clearance. Reassemble valve and perform hydrostatic test and fugitive emission leakage inspection.

Interface

Valve bonnet mounting structure, locating pin holes, no LED indicators on 75B0018X012.

Diagnostic

Stem external leakage: Packing box deformation or packing damage. Valve stem sticking: Packing box misalignment and stem friction abnormal. Fugitive emission exceed: Corrosion or scratch on packing box inner bore.
