What is the corrosion resistance of Brass Breather Valve, and in what harsh environments can they still be used normally?

A dense oxide film will form on the surface of brass, which can effectively prevent the external corrosive medium from further contacting the brass matrix, thereby playing a protective role. It can withstand corrosion from water, air, most organic matter, and high temperature and high humidity environments. For example, in humid air, Brass Breather Valve will not rust as easily as some other metals; when in contact with ordinary water, they can also maintain the stability of their structure and performance for a long time. Brass Breather Valve also have a certain tolerance to a variety of salt solutions, which allows them to be used normally in some coastal areas or in environments with salt spray. At the same time, in the face of various organic substances, Brass Breather Valve can also show good corrosion resistance and are not easily damaged by these substances.
In many industrial production sites, such as construction sites, mines, factories, etc., the air often contains a large amount of dust particles. These dusts will not only affect the normal operation of the equipment, but may also enter the inside of the breathing valve, causing wear and blockage. Brass Breather Valve are usually equipped with high-efficiency filters that can effectively filter dust particles in the air. The filter is like a barrier, blocking the dust outside the breathing valve and protecting the internal structure of the breathing valve from dust. Even in an environment with high dust concentration, the brass breathing valve can ensure the normal circulation of airflow and ensure the safe operation of the equipment.
Chemical plants, oil depots, rubber processing and other places often release various harmful gases, such as hydrogen sulfide, sulfur dioxide, chlorine, etc. These harmful gases are not only harmful to human health, but also cause serious corrosion to the equipment. The brass breathing valve can work normally in this harmful gas environment with its good corrosion resistance. The oxide film on its surface can resist the erosion of harmful gases and prevent the valve body material from being corroded and damaged. At the same time, the sealing performance of the brass breathing valve can also effectively prevent the leakage of harmful gases and protect the safety of the surrounding environment and personnel.
The temperature in workplaces such as casting, metallurgy, and glass manufacturing is usually high, which places high demands on the high temperature resistance of the equipment. The brass breathing valve has good thermal conductivity and can quickly adapt to temperature changes. In a high temperature environment, it will not be deformed or damaged by heat like some plastic or rubber valves. Brass has a high melting point and can withstand a certain high temperature without losing its mechanical properties and corrosion resistance. Therefore, in high-temperature workplaces, Brass Breather Valve can maintain stable performance and ensure the normal operation of equipment.
Various organic solvents, such as formaldehyde, ketones, esters, etc., are often used in industries such as printing, paint, and coatings. These organic solvents have certain volatility and corrosiveness. If the equipment does not have good corrosion resistance, it is easy to be corroded and damaged. Brass Breather Valve also have certain corrosion resistance to organic solvents. Its special material structure makes it difficult for organic solvent molecules to penetrate into the valve body, thereby effectively blocking the corrosion of the valve body by organic solvents. In an organic solvent environment, Brass Breather Valve can ensure the stability of sealing and mechanical properties, providing protection for the safe operation of equipment.
Although Brass Breather Valve have good corrosion resistance, special attention should still be paid in certain specific media and environments. For example, brass valves have poor tolerance to certain specific media, such as oxidizing acids such as nitric acid and concentrated sulfuric acid. These oxidizing acids are highly oxidizing and will react chemically with brass, causing the valve body to be corroded. In addition, contact with ammonia may also cause stress corrosion cracking of copper and copper alloys. In environments such as molten metal, sulfur and sulfides, Brass Breather Valve may also be damaged to varying degrees.
