Ball Valve, two of the most common connection types are threaded ball valves and flanged ball valves. Understanding their structural differences and application scenarios is essential to making the right choice for your project. Threaded Ball Valve: if you need compact design, quick installation, and cost savings for smaller pipelines. Flanged Ball Valve: if you need strength, reliability, and easier maintenance for large, high-pressure, or critical systems.
