Stainless Steel 4-Inch Pneumatic Tank Bottom Valve (HB804CQ-100RSS) – For Chemical and Water Tank Trucks
In chemical transportation and liquid logistics, safety and leak prevention are top priorities. The HB804CQ-100RSS stainless steel pneumatic bottom valve is engineered for 4-inch tank outlets and is widely used on chemical tankers, water trucks, and other liquid transport vehicles. Installed at the tank bottom, the valve disc is sealed inside the tank, while the valve body features a precision-designed cutting groove. In the event of a sudden impact, the outer portion of the valve body breaks along this groove, maintaining the overall tank seal and effectively preventing leaks.
Global Recognition and Various Names
This valve is known by different terms around the world. In Europe and North America, it is often called a “Stainless Steel Pneumatic Bottom Valve” or “Emergency Tank Valve.” In Asia, operators may refer to it as a “Chemical Tank Pneumatic Base Valve” or “Tank Floor Pneumatic Valve.” In South America, it is sometimes called “Válvula de Fondo Neumática de Acero Inoxidable.” No matter the name, its core function is to provide a secure, high-flow, and long-lasting connection for tank bottom operations.
