L Port Ball Valve

L-port ball valve (L-bore three-way ball valve) is a multi-port quarter-turn rotary valve engineered with an L-shaped fluid passage drilled through its central spherical ball to provide efficient flow-diverting and line-switching control. Acting primarily as a directional switching valve, it allows operators to steer a media stream entering a common inlet port into one of two distinct outlet ports, or conversely, alternate between two separate supply lines feeding into a single downstream line. The valve cleanly cuts off fluid delivery to one piping leg the moment it establishes connection with the other, ensuring that both paths are never simultaneously open to prevent accidental fluid blending. Piping systems layout contractors and process engineers can simplify fluid diversion loops and minimize overall valve counts by importing certified L-port ball valves directly from specialized manufacturers in China via our advanced B2B commercial platform.
