A stainless steel pneumatic head fluorine-lined diaphragm valve is a type of valve that is mainly composed of stainless steel and fluoroplastic (fluorine-lined). This valve has excellent corrosion resistance and good sealing performance, so it is widely used in pipeline systems in chemical, pharmaceutical, petroleum and other industries.
The working principle of a stainless steel pneumatic head fluorine-lined diaphragm valve is to use the diaphragm plate to move up and down in the valve body to control the on/off of the fluid. Due to the presence of fluorine-lined layer, the valve has good corrosion resistance and can effectively prevent the erosion of various chemical media. At the same time, due to the application of the pneumatic head, the valve can be controlled remotely, which is convenient for operation and management.
The advantages of stainless steel pneumatic head fluorine-lined diaphragm valves include:
A. Strong corrosion resistance: Due to the presence of a
fluorine-lined layer, the valve can resist the erosion of various
chemical media, thereby extending the service life of the valve.
B. Good sealing: The seal between the diaphragm and the valve body is a combination of metal and fluoroplastic, which has good sealing performance and can effectively prevent leakage.
C. Easy to operate: The valve can be controlled remotely through the
pneumatic head, which is convenient for operation and management.
D. Wide range of applications: Due to its excellent corrosion
resistance and sealing properties, stainless steel pneumatic head
fluorine diaphragm valves are widely used in various industries and
fields.
The stainless steel pneumatic head fluorine-lined diaphragm valve is a high-performance valve with excellent corrosion resistance and sealing properties, which can meet the fluid control needs in various complex environments.

Fluorine-lined valves, also known as fluoroplastic-lined
corrosion-resistant valves, are made of PTFE or PFA (or profiles
processed) by molding (or inlaying) on the inner wall of steel or iron
valve pressure bearings (the same method is applicable to the lining of
various pressure vessels and pipeline accessories) or the outer surface
of valve linings, and using its unique properties in strong corrosion
resistance media to make various valves and pressure vessels.
Fluorine-lined valves can use lining process for all the places that can be reached by the medium in the valve body, and the lining materials are generally made of fluoroplastics such as FEP (F46) and PCTFE (F3), which can be applied to various concentrations of sulfuric acid, hydrochloric acid, hydrofluoric acid, aqua regia and various organic acids, strong acids, strong oxidants and other corrosive media and other pipelines. However, fluorine-lined valves are limited by temperature, only suitable for mediums between -50°C~150°C, please consult our customer service for details.
Valves that can be made lined with fluorine plastics include: fluorine-lined butterfly valves,Fluorine-lined ball valves, fluorine-lined globe valve,Fluorine-lined diaphragm valves, fluorine-lined gate valves, fluorine-lined plug valves,Fluorine-lined pipe fittings、Fluorine-lined jointsetc., and accessories include (electric, pneumatic, electromagnetic, explosion-proof, filtering, adjustment, remote automatic control and other functions).
| Properties of PTFE-polytetrafluoroethylene | |
| High temperature resistance | The operating temperature is up to 250°C |
| Resistant to low temperatures | It has good mechanical toughness and maintains an elongation of 5% even when the temperature drops to -196°C |
| It is non-toxic | It has physiological inertness and has no adverse reactions as artificial blood vessels and organs implanted in the body for a long time |
| Mechanical properties | It is the smallest surface tension in solid materials, does not adhere to any substance, and its friction coefficient is extremely small, only 1/5 of polyethylene, which is an important feature of perfluorocarbon surfaces. Because the intermolecular force of the fluorocarbon-carbon chain is extremely low, PTFE is non-stick |
| Excellent insulation performance | A thick layer of newspaper film is enough to resist 1500V high voltage, |
| Chemical and weather resistance | Teflon is virtually immune to any chemical agents except molten alkali metals. For example, when boiled in concentrated sulfuric acid, nitric acid, hydrochloric acid, or even aqua regia, its weight and properties do not change, and it is almost insoluble in all solvents, and is only slightly soluble in perankanes (about 0.1g/100g) above 300°C. |
| Excellent weather resistance | It does not absorb moisture, is non-combustible, is extremely stable to oxygen and ultraviolet rays, and has the best aging life among plastics |
| Electrical performance | Teflon has low dielectric constant and dielectric loss over a wide frequency range, as well as high breakdown voltage, volumetric resistivity, and arc resistance |
