The components of a lined ball valve include the body, stem, ball, seat, and lining.
High-quality PFA or PTFE is used to line the interior, and this provides good protection against chemical corrosion. This makes these valves suitable for particularly unpleasant tasks.
These valves are widely popular as “Shut Off” because some kinds are manufactured with a free-floating design of the ball that favours Positive shut-off over the operating pressure range. As a result, these valves can be used in a variety of applications.
Lined Ball Valve v/s Unlined Ball Valve:
Similar in appearance to their unlined counterparts, lined ball valves are an economical choice for applications requiring long-term sealing and durability in harsh corrosive or chemical environments. They are suitable for use in control and shutdown applications due to their longevity, dependability, and performance even after repeated cycling.
They are suitable for automation since the ISO 5211 certified comprehensive mounting pad makes it simple to automate the valve while it is still in the pipeline, and they may be installed regardless of the direction of flow. Each lined ball valve is outfitted with its own anti-static mechanism, which safeguards against potentially harmful electrostatic discharges, and the stem design features an anti-blow-out function that offers improved safety.

How to differentiate between PTFE lined valve and PFA lined valve?
Lined valves offer a foolproof method of controlling the flow of chemicals while preventing corrosion at any concentration. The fittings as well as valves are coated so that they are resistant to chemicals and last a long time. PTFE lined valves and PFA-lined valves are frequently used as low-cost substitutes for high-grade alloys that are used in corrosive applications by various industries such as pharmaceutical, chemical, fertiliser, petrochemical, metallurgical as well as pulp and paper. Knowing the material distinctions between PFA and PTFE is essential for understanding their distinction.
Most people are familiar with PTFE, but PFA is also a common Teflon variety. PFA and PTFE share the same chemical characteristics, making both extremely strong and resistant to stress cracking in mechanical applications. Moulding, extrusion, injection, transfer moulding, and other forms of moulding are all possible thanks to the material’s malleability and versatility; this means it can be used to create everything from high-frequency insulation parts to special spare pieces for machinery to the corrosion-resistant lining for pipes, valves, and pumps.
Excellent corrosion resistance, chemical stability, electrical insulation, high lubrication and non-viscosity, sealing, as well as good ageing resistance for media like strong acid, strong alkali, and strong oxidant characterise PTFE (Teflon), a polymer compound formed by the polymerization of tetrafluoroethylene. The chemical, electric equipment, pharmaceutical, petrochemical, fertiliser, pulp and paper, and metallurgical sectors are just some of the harsh environments where PTFE-lined valves can be put to good use.

Polyfluoroalkoxy, or PFA, is an advanced thermoplastic polymer modified from PTFE that features higher performance and lower viscosity. The performance of PFA is comparable to that of PTFE, the more well-known type of Teflon, but PFA is more flexible. The ability to melt process PFA sets it apart from PTFE resins. Temperatures between -250 and 260°C may be maintained in service. It is inert to flames and is resistant to acids, bases, and alkalis as well as grease and oil. It also has a long lifespan, is not affected by heat or cold, and is impervious to ageing. Over 23 MPa of tensile strength and over 250% elongation.
Together, PFA-lined valves function substantially better than PTFE-lined valves. While PTFE valves enjoy widespread use due to their low cost, PFA valves and tubing are typically found in industrial settings. High sealing performance is ensured by the PFA lining of the valve, making it ideal for use with liquid and gas media in a wide variety of industrial pipelines, including those carrying hydrofluoric acid, sulfuric acid, nitric acid, hydrochloric acid, as well as other extremely corrosive compounds.
