The Three Way “L” Port Ball Valve also called as a Diverting Valve. Also Known as a Duplex Filter Valve. Ball has two ports One inlet and another outlet. Flow can be diverted to either direction. Generally at 90 deg.
The L valve can connect the center port to either side port, or disconnect all three, but it cannot connect the side ports together. L Port Valves have a ball that join two adjacent ports. Traditionally, they are used to direct flow between the Centre and one of two side ports.
