Lined Valves
Lined Check Valve
PTFE / PFA-lined check valves providing reliable non-return backflow prevention for highly corrosive chemical, acid, and pharmaceutical process lines.
OVERVIEW
What Is a Lined Check Valve?
Lined check valves are non-return valves featuring a continuous internal PTFE, PFA, or rubber lining that completely encapsulates all wetted metal surfaces. They allow media to flow freely in one direction and automatically prevent backflow when the pressure differential reverses, protecting pumps, compressors, and process equipment. Essential for aggressive corrosive fluids where metallic contact would cause contamination or rapid corrosion failure.
Key Features
- ✔️ Corrosion-Resistant Lining - PTFE, PFA, or FEP lining provides excellent protection against highly corrosive chemicals and aggressive media
- ✔️ Automatic Backflow Prevention - Prevents reverse flow to safeguard pumps, pipelines, and process equipment
- ✔️ Leak-Tight Sealing - Precision-engineered seating ensures reliable shut-off and minimizes process leakage
- ✔️ Low Maintenance Design - Non-return operation with corrosion-resistant construction reduces maintenance and extends service life
- ✔️ Wide Chemical Compatibility - Ideal for chemical processing, pharmaceuticals, chlor-alkali plants, petrochemicals, and other corrosive fluid handling applications
