Pneumatic clamp lining four fluorine pneumatic valve butterfly D671F images

Four fluorine pneumatic butterfly pneumatic valve D671F using polytetrafluoroethylene as sealing material, has reliable sealing and corrosion resistance, suitable for various types of industrial liquid and gas in the pipeline, Including steam gas) Transport, contain serious corrosive medium using occasion. Pneumatic line four fluorine pneumatic valve adjustment, convenient operation strict sealing performance, long service life and pneumatic valves at the ends of the shaft seal by the butterfly plate and the rotation of the pneumatic seat between base and fluorine rubber to control; Ensure the pneumatic valve axis not in contact with the cavity fluid.




four fluorine pneumatic butterfly pneumatic valve lining material:


1, PTFE (teflon F4)

applicable medium, strong acid, strong alkali, strong oxidizing agents, etc; Temperature: - 200 ~ 180 ℃

features: excellent chemical stability, has high heat resistance, cold tolerance; Friction coefficient is very low, is an excellent self-lubrication material, but mechanical performance is low, liquidity is poor, thermal expansion.

2, FEP FEP ( F46)

applicable medium: any organic solvent or reagent, thin or thick inorganic acid, alkali, ketone, aromatic hydrocarbons, chlorinated hydrocarbons, etc. ;

use temperature: - 85 ~ 150 ℃

features: mechanical, electrical, and chemical stability of basically the same as F4, but prominent advantage is still high toughness, and has excellent weatherability and radioactive.

3, 3 PE PCTEF ( F3)

medium: apply to all kinds of organic solvent and inorganic corrosion liquid ( Oxidizing acids) ; Temperature: - 195 ~ 120 ℃

features: after F4, heat resistance, electric properties and chemical stability, mechanical strength, creep properties, hardness than the F4 better.

4, poly (vinylidene fluoride, PVDF ( F2)

applicable medium: resistant to most chemicals and solvents. Temperature: - 70 ~ 100 ℃

features: the tensile strength and compression strength is better than the F4, bending resistance, weather resistance, radiation and ageing, etc. , the biggest characteristic is good toughness, easy to shape.

5, polypropylene RPP

applicable medium: inorganic salt aqueous solution of a class, the thin or thick inorganic acid, alkali solution; Temperature: - 14 ~ 80 ℃

features: one of the most light plastic, its yield, tensile and compression strength and hardness are better than that of low pressure polyethylene, there are outstanding rigidity, good heat resistance, easy forming, excellent inexpensive and modified dynamic, liquidity, bending elastic modulus increase.

6, dilute hydrocarbon PO

applicable medium: various concentration of acid and alkali salts and some organic solvents; Temperature: - 58 to 80 ℃

features: is one of the world's ideal anticorrosion material, has been widely used in large rotational molding equipment and pipe lining.

7, PVC

applicable medium: water, strong alkali, the oxidation resistance acid, chain hydrocarbon, oil and ozone, etc. ; Use temperature: 0 ~ 55 ℃

characteristics: high mechanical strength, chemical stability and good dielectric properties, oil resistance and anti senile is better also, easily dissolves and adhesion, low price.



pneumatic clamp lining four fluorine pneumatic valve D671F adjustment is in order to adapt to some to have the strong acid, strong alkali corrosive environment, in the field of petroleum, chemical, food, and other special needs, in conventional pneumatic valve in the pneumatic valve and pneumatic butterfly valve plate lining ptfe, make the medium and pneumatic valve isolation, to achieve the effect of antiseptic. Under normal conditions can replace stainless steel pneumatic valve body, have a higher cost performance.
