The PTFE Lined Gate Valve is engineered for pipeline systems handling highly corrosive and chemically aggressive media. Internal surfaces exposed to the process fluid are protected by a fluoropolymer lining, providing an effective barrier between the flowing medium and the metallic valve body.

The valve construction is specifically designed to accommodate the lining securely while maintaining reliable shut-off performance. Its chemical-resistant internal surfaces make it particularly suitable for applications where conventional metallic valves may experience rapid corrosion or deterioration.

PTFE lined gate valves can be used in chemical processing, petrochemical facilities, acid and alkali handling systems, fertilizer and pesticide production, dye manufacturing, pharmaceutical processing, wastewater treatment and other demanding industrial applications.

KEY ADVANTAGES

1. Excellent Corrosion Resistance
   Fluoropolymer-lined wetted surfaces provide strong resistance against a broad range of aggressive chemicals, acids and alkaline solutions.
2. Protected Internal Components
   Components directly exposed to the process medium are lined or protected to minimize contact between corrosive fluids and the metallic structure.
3. Low-Friction Sealing System
   PTFE, FEP or compatible fluoropolymer sealing combinations help reduce friction during valve operation and contribute to smoother opening and closing.
4. Reliable Stem Sealing
   PTFE-based packing provides effective sealing around the stem while allowing convenient inspection, maintenance and replacement.
5. Flexible Wedge Design
   The resilient gate/wedge arrangement helps accommodate minor alignment or sealing-surface variations, improving contact between sealing surfaces.
6. Tight Shut-Off Performance
   The combination of the lined flow path and carefully designed sealing surfaces provides dependable isolation for demanding chemical services.
7. Reduced Metal-to-Media Contact
   The fluoropolymer barrier isolates the process fluid from susceptible metallic surfaces, helping extend valve service life in corrosive environments.
8. Suitable for Demanding Chemical Applications
   Particularly suited to pipelines transporting corrosive chemicals, acids, alkalis and other industrial process fluids where material compatibility is critical.
