Sleeved Plug Valve

PTFE Sleeved Plug Valve Manufacturer: FlowBiz Exports

The FlowBiz PTFE Sleeved Plug Valve is a non-lubricated, quarter-turn valve that utilizes a high-grade fluoropolymer sleeve to provide a permanent, low-friction seal. Unlike traditional plug valves that require sealants, our design features a tapered plug that creates a "barrier fit" within the sleeve, resulting in a bubble-tight seal that is maintained by line pressure.

Key Features & Advantages

  • Maintenance-Free Sealing: The PTFE sleeve eliminates the need for grease or sealants, preventing product contamination and reducing maintenance costs.
  • 360° Sealing Surface: The sleeve wraps entirely around the circumference of the plug, providing a massive sealing area that is far more robust than standard ball valve seats.
  • Self-Cleaning Action: The rotation of the plug across the sleeve wipes away scale and solids, making it ideal for slurry and "dirty" services.
  • Zero Dead Cavities: Unlike ball valves, plug valves have no internal cavities where media can trap and solidify, ensuring smooth operation in sugar and resin industries.
  • Uni-body Construction: The robust body design provides structural integrity and minimizes potential leak paths to the atmosphere.
