Stuffing box packings are proven sealing solutions for use in pumps, agitators, and for spindle gaskets in regulating and control valves. Stuffing box packings are manufactured from yarns in braiding machines using various braiding types depending on dimension and packing type.
The materials used consist of organic natural fibers, organic synthetic fibers, or inorganic synthetic fibers, including: Aramid, PTFE, ramie, novoloid, panox, polyacrylic, glass, aluminium silicate,
carbon, pure graphite foil, and PTFE compounds. Depending on type and area of application, packings can additionally be manufactured with lubricants, fillers, and binding agents.
Valves are the most common components in plant construction. The Stuffing box packing, which seals the spindle passage in the valve housing ensures high operational reliability. That is why packings for the stuffing box space, gap, and the packing dimensions have to comply with specific requirements and special care. There are specific installation and commissioning instructions for TA Luft Packing sets to achieve the leakage rates required by TA Luft 2002 [VDI 2440/2220) which we can provide on request.
