Resistant Acid And Alkali Manual Operational Fluorine Lined Ball Valve
Product introduction:
Fluorine lined ball valves have the movement structure principle of ordinary ball valves, using fluorine plastic lining and investment casting precision casting for the shell. They have high strength, smooth appearance, and all parts in contact with the liquid are made of fluorine plastic. Therefore, they can be used for long-term use in corrosive pipelines and pipelines of any concentration within the range of -20 ℃ to 180 ℃. Pneumatic fluorine lined ball valve is designed for automatic opening and closing control of various highly corrosive medium pipelines. It is widely used in industries such as petroleum, chemical, dyeing, pesticide, acid and alkali production, and is currently one of the most ideal choices for anti-corrosion valve equipment.
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.
