Which Ball Valve Do You Need? Threaded Vs Flanged Explained

When it comes to industrial pipeline systems, choosing the right ball valve is essential for safe and efficient fluid control. 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.

Connection & Design:

Threaded Ball Valve:

Connected by internal or external threads. Compact, lightweight, and cost-effective. Suitable for pipelines up to DN50 (custom sizes up to DN100). Lower cost but more difficult to maintain once installed.

Flanged Ball Valve:

Connected with flanges, bolts, and gaskets. Strong, reliable, and easy to dismantle. Suitable for DN15–DN700 pipelines. Higher initial cost, but easier to service and maintain.

Applications:

Threaded Ball Valve:

Commonly used in small-diameter pipelines (typically up to DN50), low or medium pressure systems, and industrial applications such as HVAC, water supply, and chemical processes. Also suitable for temporary or mobile pipeline setups.

Flanged Ball Valve:

Widely applied in oil & gas, petrochemical, power generation, metallurgy, and large-scale water treatment projects. Especially recommended for medium to high-pressure, large-flow pipelines that require long-term stable operation and regular maintenance.

How to Choose?

✅ 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.
