Collection:Threaded Ball Valves

Explore Tameson’s wide range of 2-way brass threaded ball valves from various global manufacturers. A threaded ball valve made out of brass is used in a wide array of applications. Brass is durable and well-suited for most media. Threaded ball valves include all combinations of ports: F/F (Female/Female, which is the most common), M/F (Male/ Female), and M/M (Male/Male). There are various thread types, such as BSPP (parallel) or BSPT (tapered). 2-way threaded ball valves are operated by a manual hand lever to turn the ball 90 degrees, so they are also called quarter-turn ball valves or shut-off valves. The handle is connected directly to the ball through the stem. When the handle direction is parallel to the connecting pipe or hose, the ball valve opens and allows media to flow from the inlet through the bore to the outlet. When the handle direction is perpendicular to the connecting pipe or hose, the valve is closed, obstructing the media flow through the valve. This allows for easy visual identification on whether a two-way brass threaded ball valve is open or closed. Manual ball valves are one of the most common valves due to their simple operation, reliability, long service life, and wide range of applications.

Brass-threaded ball valves can be used with drinking water, gas, mineral oils, compressed air, and many other non-aggressive media. But they are not suitable for use with salt water or distilled water. They are operated with a handle. Turning the handle a quarter turn will open or close the valve. When the handle is in line with the pipe, the ball valve is open, and when it is perpendicular to the pipe, the valve is closed. The selection of brass threaded ball valves also includes a wide range of full-bore versions with an unobstructed flow path and excellent flow characteristics.
