Features of Lined Ball Valves

Corrosion Resistance

Lined Ball Valves have FEP, PFA, PVDF, or ceramic liners, so they handle strong acids, alkalis, and solvents and last over 10 years.

Abrasion Resistance

With a body of S.G. Iron or CF8/CF8M and a ball core of alumina ceramic, these valves resist wear from particles effectively.

Sealing Performance

The PTFE V-ring seals and hook-groove lining keep leakage under 0.05%, ensuring long-term, worry-free operation.

FAQ

Q: How to clean them?

A: The inner lining surface can be cleaned with warm water or a neutral detergent. Avoid scratching the valve body with hard objects.

Q: Is installation complicated?

A: No. The two-piece valve body design supports flanges or special interfaces, making installation simple and quick.

Q: Is maintenance difficult?

A: No, regular checks of seals and lubrication are sufficient for long-term operation.
