PTFE solenoid valve (inner wire type)

PTFE solenoid valve (inner wire type)The main material is made of polytetrafluoroethylene material. The valve body is generated by free radical polymerization of tetrafluoroethylene. The polymerization reaction in industry is carried out by stirring in the presence of a large amount of water to disperse the reaction heat and facilitate temperature control. Aggregation is generally carried out at 40-80 ℃ and 3-26 kg force/cm2 pressure. Inorganic persulfates and organic peroxides can be used as initiators, or redox initiation systems can be employed. Each mole of tetrafluoroethylene releases 171.38 kJ of heat during polymerization. Dispersion polymerization requires the addition of perfluorinated surfactants, such as perfluorooctanoic acid or its salts.

PTFE solenoid valve (inner wire type)classification

① According to the pressure level, there are two types: direct acting and pilot operated;

② According to the opening and closing form, it can be divided into two types: normally open and normally closed;

③ According to the requirements of the workplace environment, there are two types: ordinary and explosion-proof;

④ According to the power supply and voltage level, there are DC and AC (AC220V, AC110V, AC24V, DC24V, DC12V, DC36V, DC48V, etc.).

⑤ The diameter size is DN1.2-DN65.

Features:

a. Valve body, valve cover, valve core, and valve stem material: made of polytetrafluoroethylene (PTFE) material;

b. Sealing element: corrosion-resistant grade and PTFE *, can withstand various strong acids, strong alkalis, strong oxidants, and organic solvents;

c. Replacing diaphragm with piston structure;

d. The fluid is isolated from metal components such as magnetic core tubes;

e. The soft seal.

Performance:

a. Polytetrafluoroethylene is almost not corroded by any chemical reagents. For example, in concentrated sulfuric acid (98% concentrated sulfuric acid), nitric acid, hydrochloric acid, and even Wang

When boiled in water, its weight and properties remain unchanged, and it is almost insoluble in all solvents;

b. Polytetrafluoroethylene does not absorb moisture, otherwise it is extremely stable to oxygen and ultraviolet radiation, so it has properties such as weather resistance, oxidation resistance, resistance to surface fouling, anti fading, and anti brittleness;

c. Non polluting, non-toxic, odorless, with high purity and chemical inertness, it will not have any impact on the fluid medium;

d. Temperature range: -30 ℃ to+180 ℃.
