Fluorine-lined Ball Valve Manufacturers Briefly Analyze What Is A Fluorine-lined Electric Ball Valve

Lined Ball Valve is lined with fluoroplastics, combined with a new rod ball structure and a unique elastic lip seal seat structure. It has the advantages of ordinary ball valves, with high sealing performance and low operating torque within a large pressure difference and temperature difference range. It can be used for switching or regulation. This product is suitable for the transportation of liquids and gases (including steam) in various industrial pipelines, and can work in various highly corrosive media such as acids, alkalis, and salts. The flow provided by the full-diameter valve can be used to clean or isolate the conveying pipeline.

Fluorine-lined electric ball valves are professionally designed to control the opening and closing of various highly corrosive media. They are widely used in petroleum, chemical, dyeing, pesticide, acid and alkali production industries, and are currently the ideal choice for anti-corrosion valves.

The main lining material of fluorine-lined electric ball valves - fluoroplastics:

Polytetrafluoroethylene FEP (F46)

Applicable media:

Any organic solvent or reagent, dilute or concentrated inorganic acid, alkali, ketone, aromatic hydrocarbon, chlorinated hydrocarbon, etc.

Fluorine-lined electric ball valve use temperature:

-85~150

Features: Mechanical, electrical properties and chemical stability are basically the same as F4, but the outstanding advantage is dynamic toughness

High, with excellent weather resistance and radiation.

Polytrifluoroethylene PCTEF (F3)

Applicable media edit

Various organic solvents, inorganic corrosive liquids (oxidizing acids)

Use temperature: -195~120

Features: Heat resistance, electrical properties and chemical stability are second only to F4, mechanical strength, creep performance, hardness is better than F4

Polypropylene: RPP

Applicable media: Aqueous solutions of inorganic salts, dilute or concentrated solutions of inorganic acids and alkalis.

Use temperature: -14~80

Features: One of the lighter plastics, its yield, tensile and compressive strength, hardness are better than low-pressure polyethylene, with outstanding rigidity, good heat resistance, easy molding, and low cost. After modification, dynamic impact, fluidity, and bending elasticity.

Polyvinyl chloride: Rigid) PVC

Applicable media: water-resistant, concentrated alkali, non-oxidizing acid, chain hydrocarbon, oil and ozone, etc.

Using temperature: 0-55

Features of fluorine-lined ball valve: high mechanical strength, excellent chemical stability and dielectric properties, good oil resistance and aging resistance, easy to weld

and bond, low price.

Polytetrachloroethylene PTFE (F4)

Using medium: strong acid, strong alkali, strong oxidant, etc.

Using temperature: -200~180

Features: It has excellent chemical stability, high heat resistance, cold resistance, low friction coefficient, and is an excellent self-lubricating material, but has low mechanical properties, poor fluidity, and large thermal expansion.

Polyvinylidene chloride PVDF (F2)

Using medium: resistant to most chemicals and solvents,

Using temperature: -70~100

Features: tensile strength and compression strength are better than F4, resistant to bending, weathering, and radiation. Light-resistant and aging-resistant, the biggest feature is good toughness and easy molding.

Polyolefin: PO

Applicable media: various concentrations of acids, alkalis, salts and certain organic solvents.

Using temperature: -58~80

Features: It is the world's ideal anti-corrosion material, and has been widely used in large-scale rotational molding equipment and pipeline linings
