Product Video

Screwed End 3 Way Ball Valves feature threaded connections (NPT / BSP) for direct installation into pipeline systems without welding or flanging. These valves are primarily used for:

Flow diversion (one inlet to two outlets)
Flow mixing (two inlets to one outlet)
Line switching operations

Working Principle

The internal ball has either an L-shaped or T-shaped bore. By rotating the lever 90°, flow direction is changed or combined depending on the configuration. The threaded ends allow fast assembly and removal without hot work, making them suitable for maintenance-friendly installations.
