Product introduction:
Fluorine lined valves are equipment used for lining various pressure vessels and pipeline accessories
Fluorine lined valves, also known as fluorine plastic lined corrosion-resistant valves, are made by placing polytetrafluoroethylene resin (or processed profiles) on the inner wall of steel or iron valve pressure parts (the same method is applicable to the lining of various pressure vessels and pipeline accessories) or the outer surface of valve interiors using its unique performance in resisting strong corrosive media to make various types of valves and pressure vessels.
Polytetrafluoroethylene, commonly known as the "plastic king", was first developed and introduced by DUPONT CO., LTD. in 1938 in the United States. It underwent industrial production in 1949 and has a history of 50 years from an industrial application perspective. However, it has not been widely used in the valve industry for a long time.
Fluorine lined valves use lining technology for all areas within the valve body that can be reached by the medium. The lining material is generally made of fluoroplastics such as FEP (F46) and PCTFE (F3), which can be used in pipelines with various concentrations of sulfuric acid, hydrochloric acid, hydrofluoric acid, aqua regia, and various organic acids, strong acids, strong oxidants, and other corrosive media. However, fluorine lined valves are limited by temperature (only suitable for media between -50 ℃ and 150 ℃). Valves that can be lined with fluoroplastics include fluorine lined butterfly valves, fluorine lined ball valves, fluorine lined globe valves, fluorine lined diaphragm valves, fluorine lined gate valves, fluorine lined plug valves, etc.
Classification and application of plastic raw materials:
|
No. |
Material | Working temperature | Medium application | Characteristics |
| 1 | FEP (F46) |
-85~150℃
|
Any organic solvent or reagent, dilute or concentrated inorganic acid, base, ketone, aromatic hydrocarbon, chlorinated hydrocarbon, etc | The mechanics, electrical properties, and chemical stability are basically the same as F4, but the outstanding advantages are high dynamic impact toughness, excellent weather resistance, and radiation resistance. |
| 2 | PCTEF (F3) | -195~120℃ | Various organic solvents, inorganic corrosive liquids (oxidizing acids) | Heat resistance, electrical performance, and chemical stability are second only to F4, while mechanical strength, creep performance, and hardness are better than F4 |
| 3 | RPP | -14~80℃ | Aqueous solutions of inorganic salts, dilute or concentrated solutions of inorganic acids and bases. | One of the lightest plastics, it has superior yield, tensile and compressive strength, hardness compared to low-pressure polyethylene, outstanding rigidity, good heat resistance, easy molding, and cost-effectiveness. Modified dynamic impact, fluidity, and bending elasticity. |
| 4 | PVC | 0-55℃ | Resistant to water, concentrated alkali, non oxidizing acids, hydrocarbons, oil, and ozone. | High mechanical strength, good chemical stability and dielectric properties, good oil resistance and anti-aging resistance, easy fusion and bonding, low price. |
| 5 |
PTFE (F4)
|
-200~180℃ | Strong acids, strong bases, strong oxidants, etc. | It has excellent chemical stability, high heat resistance, cold resistance, and low friction coefficient, making it an excellent self-lubricating material. However, its mechanical properties are low, its flowability is poor, and its thermal expansion is large. |
| 6 | PVDF (F2) | -70~100℃ | Resistant to most chemicals and solvents | Lashen has better strength and compression strength than F4, with resistance to bending, weather, and radiation. It is resistant to light and aging, and its biggest feature is good toughness and easy molding |
| 7 | PO | -58~80℃ |
Various concentrations of acid, alkali, salt, and certain organic solvents.
|
It is the world's most ideal anti-corrosion material and has been widely used for the lining of large equipment and pipeline components in rotary molding.

Product in industries:
Product advantages:
The fluorine lined valve has dual functions of switch and flow regulation, which can easily open and close the gas circuit without affecting the flow rate, ensuring the repeatability of the flow rate. The slow opening reduces the impact of instantaneous pipeline pressure on the instrument. By adding a damper, the service life of the fluorine lined valve is greatly extended. Fluorine lined valves are specifically designed to control corrosive or highly corrosive media. The inner surface of the valve body is covered with various fluoroplastics for selection, suitable for different working temperatures and fluid pipelines. They have the characteristics of high strength and good corrosion resistance.
