Wafer Type Butterfly Valve PTFE Lined

The lining material of the Wafer Type Butterfly Valve is fluoroplastic. The following is the performance of on the industrial product of fluoroplastics:
Polytefluorophosphate FEP (F46)
Applicable medium:
Any organic solvent or reagent, sparse or thick -ingredients, alkali, ketones, aromatics, chlorine chloride, etc.
Operating temperature:
-85 ~ 150
Features: mechanics, electrical properties and chemical stability are basically the same as F4, but the prominent advantage is the dynamic toughness
High, with excellent weather resistance and radiation.
Polytestein PCTEF (F3)
Applicable medium:
Various organic solvents, inorganic corrosion liquids (oxidized acid)
Use temperature: -195 ~ 120
Features: heat resistance, electrical performance and chemical stability are second only to F4, mechanical strength, creep performance, hardness than F4
Polypropylene: RPP
Applicable medium: water solution of inorganic salts, inorganic acids, and alkali are sparse or thick solution.
Use temperature: -14 ~ 80
Features: One of the lightest plastics, its yield, stretching and compression strength, and hardness are better than low -pressure polyethylene. It has very prominent rigidity, good thermal resistance, easy to form, and cheap. Moisture, liquidity, bending elasticity after modification.
Polyethylene: Hard) PVC
Applicable medium: water resistance, thick alkali, non -oxidized acid, chain hydrocarbons, oil and ozone, etc.
Use temperature: 0-55
Features: high mechanical strength, excellent chemical stability and dielectric performance, good oil resistance and aging resistance, easy to melt
And bonding, the price is low.
Polytetthylene PTFE (F4)
Use medium: strong acid, strong alkali, strong oxidant, etc.
Use temperature: -200 ~ 180
Features: It has excellent chemical stability, high heat resistance, cold resistance, and low friction coefficient. It is an excellent self -lubricating material, but the mechanical properties are low, the liquidity is poor, and the thermal expansion is large.
Poly chlorine PVDF (F2)
Use medium: resistant to most chemicals and solvents,
Use temperature: -70 ~ 100
Features: The intensity and compression strength of the gentleness are better than F4, resistant to folding, weather -resistant, and radiation. Light resistance and aging, the biggest feature is good toughness and easy to form.
Polystide: PO
Applicable medium: a variety of concentrations of acid -base salt and certain organic solvents.
Use temperature: -58 ~ 80
Features: It is the most ideal anticorrosive material in the world. It has been widely used for large -scale equipment and pipeline lining for rotating molding.
