Lined Ball Valve
Our PFA lined ball valves are designed for handling aggressive corrosive conditions, ensuring long-term durability under the harshest conditions. With exceptional corrosion resistance, these valves are used in industries like chemical processing, chlor-alkali, mining, petrochemicals, pulp and paper, steel, pharmaceuticals, and wastewater treatment. We also offer ball valves with FEP/PVDF/ETFE/ECTFE & PPH liners.
Our ball valves can operate in a wide temperature range (- 40°C to 200°C) and can withstand pressures up to 15 bar . Certified for CLASS VI – Tight Shutoff as per API 598, these valves have zero leakage ensuring safe and reliable operations.
Our ball valves come with versatile operational options—choose from a robust cast iron lever, handwheel, electric, or pneumatic actuator for effortless control. The PTFE seats ensure low-friction performance and high endurance, while our single-piece shaft and ball, uniformly lined with PFA, ensures corrosion free long-lasting service. Available in sizes from DN15 – DN 300 ( 1/2” to 12”), our valves are ready to meet the demands of your project.
With decades of industry expertise, our team is dedicated to delivering high-quality, cost-effective solutions tailored to your needs.

FAQ's
A PFA-lined ball valve features a body lined with PFA (Perfluoroalkoxy alkanes) and a ball lined from PFA, providing excellent corrosion resistance and low permeability. This makes it ideal for handling aggressive chemicals, where standard valves may not be suitable.
PFA lining offers high chemical resistance, a smooth surface that minimizes friction and fouling. The PFA lining acts as a barrier between the flowing medium and the valve's internal components, effectively shielding them from corrosive substances.
Yes, these valves generally require minimal maintenance. Regular inspection for wear and tear, along with routine cleaning, can help ensure their longevity
Ball valves consist of a spherical ball with a bore that is rotated to open or close the valve. When aligned with the valve body, the bore allows fluid flow; when perpendicular, it seals the valve.
PFA lined ball valves have a specialized PFA liner on the inside of the valve and the trim insert, making them ideal for corrosive environments, where standard valves may not be suitable.
These valves offer quick opening, full bore operation, and low pressure drop, suitable for automated or manual use in shutoff, throttling, and flow control of of liquids, gases, and slurries, ensuring tight sealing and efficient operation.
Yes, these valves find extensive application in Chlor-Alkali industries handling aggressive chemicals like hydrochloric acid and caustic soda.
Certainly! We offer Antistatic PFA lined Valves in Dupont's grade C 980 or 3M Dyneon's 8502 ESDZ. Choosing the correct material is crucial, as a grounding spring alone cannot dissipate static charge in a standard PFA grade, which is non-conductive.
We keep many valves in stock in our warehouse in Netherlands, India and USA and can ship them within a week.
Our ball valves are available in numerous sizes DN15-DN300 (1/2"-12") providing a range of options to meet diverse industrial needs.
