Corrosion-resistant steels include stainless steel, special steel, "Monel" alloy, Hastelloy "B", Hastelloy "C", stainless and acid-resistant steel, etc.
Acid-resistant stainless steel valves can be widely used in chemical, food and other industries. For example, pipelines for acetic acid, nitric acid, sulfuric acid, alkali, bleach, food, fruit juice, carbonic acid, leather liquid and many other chemical products. Ultra-low temperature austenitic anti-rust steel valve, supply solenoid valve is often used to transport liquid gas at low temperature, such as natural gas, biogas, oxygen, hydrogen, etc.
Special stainless steel valves have good corrosion resistance, and are usually used in various temperatures and concentrations of sulfuric acid pipelines and equipment. It is mainly used to transport alkali, salt solution, food and many inorganic acids, especially sulfuric acid and hydrofluoric acid pipelines and equipment "Monel" alloy valve.
In addition, this valve can also be used in steam and sea water pipelines. The two-way solenoid valve is a nickel valve with strong corrosion resistance to lye and salt. It is usually used for product transportation and requires high-purity working conditions. It is mainly used for "Hastelloy" alloy valves on pipelines and equipment that transport ammonium chloride, zinc chloride, aluminum sulfate, ammonium sulfate, hydrochloric acid and other strong corrosive media.
Valves are classified according to the material of the valve body.
Metal material valve: Its valve body and other parts are all made of metal material. For example, cast iron valves, carbon steel valves, alloy steel valves, copper alloy valves, aluminum alloy valves, lead alloy valves, titanium alloy valves, Monel alloy valves, etc.
Non-metallic material valve: its valve body and other parts are all made of non-metallic material. Such as plastic valve, ceramic valve, enamel valve, glass fiber reinforced plastic valve.
Metal valve body is lined with valve: The valve body is made of metal, and the main surface in contact with the medium is lined, such as rubber-lined valves, plastic-lined valves, and ceramic-lined valves.
