High-Reliability Manual Bottom Valve for Tank Trucks
The HB804CS-100 series manual bottom valve is a mechanically controlled valve specifically designed for fuel tank trucks, combining safety, durability, and high flow performance. Installed at the bottom of the tank, the valve disc is sealed inside the tank, while the valve body features a cutting groove. In the event of an unexpected severe impact, the outer part of the valve body will break along the groove, ensuring the overall sealing of the tank and effectively preventing fuel leakage, thus safeguarding loading and unloading operations.
This manual valve operates through mechanical control, providing precise and reliable operation during fuel transfer processes. The optimized internal design ensures smooth flow during loading and unloading while minimizing leakage risks. The valve body is made of aluminum with surface oxidation treatment, offering corrosion resistance and long-lasting durability. Optional VITON or Buna-N seals enhance chemical resistance and extend service life.
Globally, this type of manual bottom valve is known by various names depending on the region. In Europe and North America, it is often referred to as a "Manual Emergency Shut-off Valve" or "Tank Truck Bottom Valve." In the Middle East and Southeast Asia, it is called "罐底手动阀" or "油罐车底部紧急阀." In South America and other Latin American countries, it may be known as "Válvula manual de fondo para cisterna." Regardless of the terminology, its core function remains consistent: providing a reliable and safe bottom valve control solution for fuel transportation.
