Heavy-Duty Tank Side Welding Sump / Male Bolt Flange for Bottom Valve Installation

Heavy-Duty Tank Side Welding Sump / Male Bolt Flange for Bottom Valve Installation

The HBBVTSFL-XXXRB series provides a robust solution for connecting EN13308 standard bottom valves to fuel tanker bodies, chemical trailers, or other hazardous liquid transport vehicles. Designed for direct welding to the tank bottom outlet, these flanges serve as a solid, leak-proof base for reliable valve installation. The pre-welded male bolts simplify mounting, ensuring precision alignment and a secure connection for 3-inch, 4-inch, or 6-inch bottom valves.

Constructed from either carbon steel or stainless steel, this series balances strength with corrosion resistance, making it ideal for fuel, chemical, or industrial liquid handling. The precision-machined flange surface guarantees tight sealing, reduces the risk of leakage, and allows easy installation of bottom valves, even under demanding operational conditions.

Globally, this type of product is referred to by a variety of names depending on the region: Tank Side Welding Sump, Male Bolt Flange, Bottom Valve Tank Adapter, Fuel Tank Connection Flange, Chemical Tank Welding Flange, Industrial Liquid Tank Mounting Plate, EN13308 Bottom Valve Interface, or Oil Truck Tank Flange. Despite differences in terminology, all highlight the product’s primary function: secure, durable, and leak-proof bottom valve installation.
