What is the difference between flange ball valve and internal thread ball valve

Aug 05, 2025 Leave a message

Flanged ball valves and internally threaded ball valves are two common types of ball valves, differing primarily in their connection methods and applicable scenarios.

 

1. Connection Methods:

Flanged ball valves: Flanged ball valves use flanges to secure the connection between the valve and the pipe. Flange connections can be threaded, butt-weld, or nut flanges, offering strong connection strength and sealing performance.

Internally threaded ball valves: Internally threaded ball valves use threads, meaning corresponding internal threads connect the valve body and the pipe. Threaded connections are simpler than flange connections, but offer relatively poor sealing performance.NPT ball valve

2. Applications:

Flanged ball valves: Flanged ball valves are suitable for applications with high pipeline pressures, large flows, and high frequency of use. Due to the stable structure and excellent pressure resistance of the flange connection, they are suitable for various industrial applications involving liquids and gases.

Internally threaded ball valves: Internally threaded ball valves are suitable for applications with lower pipeline pressures and low temperatures. Their simple threaded connection structure makes them suitable for controlling low-pressure liquids or gases.

In short, there are some differences between flange ball valves and internal thread ball valves in connection methods and applicable scenarios. Choose the appropriate ball valve type according to specific usage requirements and working conditions.
