Detail Information

Product Name: Duplex-braided Valve Packing
Type: Valve Stem Packing
Material: PTFE, Graphite, Fluoropolymer
Diameters: 3 mm to 50 mm
Pressure: 25 MPa/250 bar
pH Range: 3–14
Tmperature Range: -100°C to 250°C

Key Features

Dense construction with high resilience and integrated break-in lubricant for improved sealing.
Both yarn components are highly lubricated during manufacture; the fluoropolymer-based yarn releases lubricant on the packing’s inside diameter during shaft rotation.
Provides smooth pump start-up and reduces friction to protect shafts and sleeves from wear.
Graphite content enhances heat dissipation, extending packing service life.

Typical Applications

Suitable for dynamic and static sealing duties across multiple industrial sectors, including:
Pumps, valves, mixers, and reactors
Cooling water pumps and condensate extraction systems
Demineralised water, raw water
Hydrocarbons, paints, synthetic resins
Emulsions, viscous slurries, and various industrial media

The packing is a duplex-braided combination packing specifically designed for industrial water duties. It consists of red fluoropolymer-based yarn and expanded PTFE yarn intimately bonded with graphite, forming a dense, resilient packing that incorporates a break-in lubricant for optimal performance.
