3-Way L Port Ball Valve

ALIS Valves offers 3-Way L-Port Ball Valves for industrial applications requiring reliable flow diversion and selective switching between multiple pipeline connections. These valves feature a specially designed ball with an L-shaped internal passage that connects two ports at a time, depending on the ball’s rotational position. This configuration is commonly used to divert flow from a common inlet to one of two outlets or to select between two inlet lines leading to a common outlet. Unlike a T-port design, an L-port arrangement is generally intended to switch flow paths rather than connect all three ports simultaneously. Depending on the application, the valve can be configured with suitable body materials, ball construction, seat materials and sealing components to meet the required process conditions. Manual, pneumatic or electric actuation options may be available for local operation, remote switching and integration with industrial automation systems.

3-Way L-Port Ball Valves are used in chemical processing plants, water treatment facilities, pharmaceutical manufacturing, industrial fluid distribution systems, heating and cooling circuits and other applications requiring selective flow routing. Depending on the specified materials, pressure rating and sealing arrangement, they can be selected for compatible liquids and gases within their rated operating limits. Important selection factors include valve size, port configuration, required flow direction, operating pressure, temperature range, process media, body and ball materials, seat design and connection type. Buyers should review the valve’s porting diagram to confirm that the selected switching positions provide the intended flow path and isolate the unused port as required. For automated applications, actuator rotation, control signal, operating sequence and positioning accuracy should also be considered. Selecting the correct L-port configuration helps support efficient flow diversion, dependable switching and reliable operation under the intended working conditions.
