How to differentiate between PTFE lined valve and PFA lined valve
                     How to differentiate between PTFE 
lined valve and PFA lined valve? 
 
 
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. Are you looking for the best PTFE Lined Ball

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.
