Aramid PTFE packing for valve sealing

Aramid PTFE Packing

Aramid PTFE Packing braided from high-quality Aramid(Kevlar)yarns which are uniformly impregnated with PTFE dispersion. The braided packing shows good chemical resistance, high elasticity, and very low cold flow. It is wear-resistant but may damage the shaft if not used properly.

The aramid fiber can be braided in many types for different applications, such as  Aramid PTFE Packing with lubricant for a slurry service application, Spun aramid fiber packing with economical use; PTFE packing with Aramid corner, Graphite PTFE Packing with Aramid Corner, GPTFE & Aramid in Zebra braided packing, etc.

Feature

  1. It is wear-resistant, and it is better to use with the minimum shaft hardness of 60HRC
  2. Compared with other kinds of packing, Aramid PTFE Packing can resist more severe media and higher pressure.
  3. For hot water applications, Aramid Fiber Packing can be used un-cooled at temperatures up to 160°C.
  4. It can be used as stand-alone packing or in combination with others as an anti-extrusion ring.

Application

Aramid Fiber Packing Applications:

General-Purpose Packing: Widely used in various industrial fields, including chemical, petroleum refining, pharmaceutical, food, sugar, paper, and power industries.

Durable and Reliable: Suitable for abrasive media containing solid particles.

Recommended for: Superheated steam, solvents, liquefied gases, syrups, and other abrasive fluids.

Temperature Resistance: Can be used in hot water up to 160°C without the need for cooling fluid.

Versatile Usage: Can be used alone or combined with other braided packing materials, placed at both ends as anti-extrusion rings.
