PTFE Lined Plug Valves
PTFE Lined Plug Valves are corrosion-resistant, quarter-turn valves designed to provide reliable shut-off for aggressive and hazardous chemicals in process applications.
Product Overview
Our PTFE-lined plug valve delivers outstanding performance in even the most corrosive, high-temperature, or high-pressure environments. Engineered with a cavity-free PTFE sleeve, this valve ensures tight sealing, minimal friction, and long service life—ideal for chemical, petrochemical, pharmaceutical, food processing, and water treatment industries.
Key Features & Benefits
PTFE lining (also available in PFA and FEP) for unmatched chemical and corrosion resistance
Cavity-free design locks the lining securely in place for optimal sealing and no contamination risks
Low friction and quick quarter-turn operation, offering high efficiency and ease of use
Wide size range: ½″ to 12″ (15 NB–300 NB) to meet diverse installation needs
Pressure rating: ANSI Class 150/300, PN10/PN16—high pressure and low-pressure drop capable
Temperature range: –40 °C to +200 °C (extended for specific models)
Operational options: Manual, Electric, Pneumatic, or Hydraulic actuated
Flanged, threaded, or welded ends available for versatile installation
External adjustment bolts for easy in-line seal maintenance—no need to dismantle the valve
