If you’re wondering what the difference is between a Fluorine Lined Valve and a PTFE Valve, read on. PTFE valves are made of polytetrafluoroethylene, a material that is extremely flammable and can rupture when subjected to high pressure. In most cases, manufacturers choose the type sample with a nominal pressure of 2.5 MPA, but special working conditions may require a different medium.
PTFE
PTFE FLUORINE Lined valves are designed for use in pipelines that are subjected to corrosive gas or liquid media. They are corrosion resistant and can withstand various levels of organic acid, strong oxidants, and other chemical solutions. They also possess good anti-fouling and anti-sticking properties. They have a wide range of applications, including pharmaceutical and food processing industries.
These valves are typically used in chemical, pharmaceutical, and food processing. They are typically used for conveying chemicals. The highly acidic and corrosive chemicals used in these applications can eat away at steel piping. For this reason, a PTFE lining is a better choice. PTFE lining can be applied to steel pipes, elbows, reducers, and spacers.
PTFE is a non-reactive material that can maintain its dielectric properties over a wide temperature range. Moreover, it does not react with process liquids. Its low-cost and durable properties are attractive to many industries. PTFE is ideal for multi-purpose plants that deal with a variety of fluids. It can achieve cleanliness levels of less than one part per billion – the same as the population of three and a half billion people. However, PTFE does have some drawbacks.
PTFE fluorine lining is a major advantage for a PTFE butterfly valve. The valve’s seat is integrated with the lining of the valve body. Its four-pole sealing structure provides a high degree of sealing performance. The fluorine-lined valve also features a high-quality silicone rubber gasket at the base of the valve seat, which makes it ideal for applications that require reliable sealing.
PTFE fluoride lining is the only material that can achieve this. It has no flammability potential, which makes it a good option for high-temperature environments. In addition, it is compatible with most chemical-safe materials and solvents. A PTFE fluoride-lined valve can withstand temperatures up to 750 degrees Fahrenheit. This material is resistant to acids, oxidizing agents, and alkalinity.
PTFE lining
The PTFE lining of a FLORINE LINED valve is a thermoplastic that is widely used in hydraulic piping. The material’s high resistance to high temperatures makes it an ideal choice for valve lining. It is also cheap and easy to form. Its bending elastic modulus and fluidity make it ideal for a wide range of applications. The following are some of its main benefits.
PTFE offers excellent corrosion resistance. It is widely used in fluids containing a high concentration of acid or an organic solvent. It has low static and dynamic friction coefficients and has excellent anti-fouling properties. PTFE is highly resistant to high temperature fluids and flammables. As a result, it can withstand high temperatures while providing excellent anti-fouling and anti-sticking properties.
Another benefit of fluorine lining is its ability to resist corrosion. It is resistant to corrosive media that would normally eat away at other valves. Fluorine lined valves are widely used in chemical, pharmaceutical and petroleum industries. Because they are corrosion resistant, they can handle all types of chemical media. The temperature range is 50 to 150°C. These valves are suitable for both harsh chemicals and hot liquids.
Remarks
PTFE has excellent transparency and transmits ultraviolet and visible light. PFA is also highly resistant to ozone and sunlight. In addition, PFA exhibits excellent mechanical strength under high temperatures and is transparent. It is used where purity and transparency are important. PTFE and FEP linings are often a combination of both materials. It is also widely used in pulp and paper operations and sulphuric services.
PTFE-LINED valves can be used in pharmaceutical and chemical processing applications. They are useful in conveying chemicals that could otherwise eat away at steel piping. With PTFE-lined valves, the highly acidic liquids and gases are not corroded by steel piping. They are also equipped with an elastic gasket that is resistant to heat and aging. Because of this, a PTFE-lined valve can achieve zero leakage.
