Brake Foot Valve is one of the vital components in the automotive braking system, and its performance and reliability are directly affected by the selected materials. Correct selection of materials can improve the durability, corrosion resistance and reliability of the Brake Foot Valve, ensuring the safety and performance of your vehicle's braking system. When it comes to material selection, there are several key factors to consider:
Wear resistance:
Since the Brake Foot Valve is subject to high-frequency working pressure and motion friction in the braking system, materials with good wear resistance need to be selected. Commonly used wear-resistant materials include stainless steel, aluminum alloy, titanium alloy, etc. They have high hardness and surface finish, which can effectively reduce wear caused by friction and extend the service life of the Brake Foot Valve.
Corrosion resistance:
Due to the particularity of the automotive working environment, the Brake Foot Valve needs to be able to resist the erosion of various corrosive media, including water, salt water, grease, etc. Therefore, when selecting materials, priority should be given to materials with good corrosion resistance. Stainless steel is a commonly used corrosion-resistant material with excellent corrosion resistance and can work stably for a long time in harsh environments.
High temperature resistance:
In the automotive braking system, the Brake Foot Valve will be affected by high temperatures, especially the friction heat generated during braking, which will cause local temperature increases. Therefore, choosing materials with good high temperature resistance is crucial to ensure the stability and reliability of the Brake Foot Valve. Titanium alloy is a commonly used high-temperature resistant material. Its high melting point and excellent heat-resistant properties make it an ideal choice for manufacturing high-temperature working parts.
Sealing performance:
Brake Foot Valve needs to have good sealing performance during work to prevent air pressure leakage and intrusion of external media. Therefore, the sealing performance of the material and its compatibility with the seal need to be considered when selecting materials. Some elastomer materials with good elasticity and wear resistance, such as fluorine rubber (FKM), nitrile rubber (NBR), etc., are often used to make seals to ensure good sealing performance of the Brake Foot Valve.
