Lined Valves
Lined Globe Valve
- Excellent Corrosion Resistance: All flow surfaces lined with fluorine, capable of resisting almost all chemical media erosion
- Good Sealing Performance: Globe valve structure with tight sealing surface contact for reliable sealing
- High Regulation Accuracy: Suitable for flow regulation with high regulation accuracy
- Small Opening/Closing Torque: Reasonable structural design with relatively small opening/closing torque
- Long Service Life: Fluoroplastic lining is corrosion-resistant with long service life
- Wide Application Range: Suitable for various corrosive media
Lined Globe Valve is a special valve based on the traditional globe valve, with a layer of fluoroplastic (such as PTFE, FEP, PFA, etc.) lining on the inner surface of flow-contacting components such as the valve body, disc, and stem. This design enables the valve to effectively resist the erosion of corrosive media such as strong acids, strong alkalis, and organic solvents, while maintaining the advantages of globe valves such as good sealing performance and high regulation accuracy. Lined Globe Valves are widely used in corrosive medium pipeline systems in industries such as chemical, petrochemical, pharmaceutical, pesticide, and dye, especially suitable for applications requiring precise flow control.
