HBBVPSFL Series Pipe Side Square Flange – Bottom Valve to Pipe Connection Solution

The HBBVPSFL series pipe side square flange provides a reliable solution for connecting bottom valves to the pipe system on tank trucks. With precise design and robust construction, this flange ensures a secure interface between the valve and the piping, maintaining excellent sealing and stable operation for smooth, leak-free liquid transfer. The flange can be welded directly to the end of the pipe, providing a solid base for bottom valve installation, making it ideal for fuel transport, chemical tankers, and other sensitive or hazardous liquid transport vehicles.

This series offers material options including carbon steel, stainless steel, and aluminum alloy, allowing selection based on specific application requirements for corrosion resistance or lightweight design. The aluminum alloy version reduces weight while maintaining reliable connection integrity, making it suitable for modern tank truck designs.

The flange is compatible with EN13308 standard 3-inch and 4-inch bottom valves. High-precision machining ensures tight sealing, easy alignment during installation, and long-term operational reliability.

This product series is widely applied across multiple industries, including fuel distribution, chemical transport, and other liquid handling operations, providing a standardized, durable, and safe solution for tank truck pipe connections.
