Key Features
Optimized leakage control in hard-working, frequently operated control valves and plug valves.
High mechanical and thermal stability ensures durability under severe conditions.
Excellent recovery characteristics maintain effective sealing after compression cycles.
PTFE suspensoid acts as a blocking agent to minimize leakage paths.
Efficient heat dissipation without chemical hardening for long service life.
Easy installation and smooth removal during shutdown maintenance.
Typical Applications
Ideal for use in control and plug valves that require frequent operation, especially in systems handling:
Hydrocarbons and petrochemicals
Superheated and saturated steam
Organic and inorganic chemicals, acids, and alkalis
Solvents, amides, fuel oils, lubricating oils
Dyestuffs, paints, and synthetic resins
The packing is an advanced gland packing designed specifically for frequently operated control valves. It features a high-strength carbon yarn core, heavily lubricated with a specialized fluoropolymer dispersion and treated with an inorganic passive corrosion inhibitor. The outer jacket is braided from pure PTFE yarn impregnated with a PTFE suspensoid lubricant, providing superior sealing performance under demanding operating conditions.
