Pneumatic valve fluorine-butterfly use instructions

a, pneumatic valve fluorine-butterfly chemical properties:
the atmospheric aging resistance, radiation resistance and low permeability: long-term exposure to the atmosphere, surface and performance remains the same.
incombustible, limit oxygen index in the following.
acid-proof alkaline, not soluble in strong acid, strong alkali and organic solvents.
oxidation resistance, corrosion ability strong oxidizer.
2, pneumatic valve fluorine-butterfly work features:
performance: media working temperature: - ℃~ - ℃
work medium pressure: positive pressure:. MPa, room temperature resistance to negative pressure KPa
corrosion resistance: steel ptfe pipe, in addition to the molten metal lithium, potassium, sodium, chloride, fluoride trifluoride oxygen under high temperature, high velocity of liquid fluorine, it can resist almost all chemical substances, including corrosion of nitric acid and aqua regia, it can be in ℃ - for a long time ℃ temperature. Steel poly (vinylidene fluoride class or other types of vinylidene fluoride compound pipe, the halogen, halogenated hydrocarbon, strong oxidant, boiling acid, alkali and a variety of organic solvents has good corrosion resistance, but not fuming sulfuric acid resistance, heat concentrated sulfuric acid and nitric acid, ℃ above ketone, esters, amines, and high temperature corrosion of sulfonating agent.
the major advantages of the pneumatic valve fluorine-butterfly:
high temperature - — Using work ℃ temperature.
low temperature - — Have good mechanical toughness; Even if the temperature dropped to - ℃, also can keep the % elongation.
corrosion - — To most chemicals and solvents, inert, acid alkali, water and a variety of organic solvents.
climate - — In the best aging with a plastic life.
high lubrication - — Is the lowest in the friction coefficient in solid materials.
don't stick - — Is the smallest, the surface tension of the solid materials don't adhere to any material.
non-toxic - — Has physiological inertia and biological non-toxic
fluorine-butterfly pneumatic valves are mainly used:
fluorine-butterfly pneumatic valves are suitable for high temperature strongly corrosive gas and liquid, and other types of inspecting &controlling and tube is not transport medium, steel ptfe composite. A tube are applicable, steel polyvinylidene fluoride compound pipe applicable conveyor working temperature in - class ℃ ~ + ℃ corrosive medium.
