L Port Ball Valve
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.
T Port Ball Valve
The Three Way “T” Port Ball Valve also known as a Mixing Valve. Ball has three ports.
It is easy to see that a T valve can connect any pair of ports, or all three, together, but the 45 degree position which might disconnect all three leaves no margin for error. T-Port valves can also direct flow between the centre and one of two side ports. The difference is that they have a third handle position that connects the centre to both side ports at the same time.JD Multiport 3 Way Ball valves utilize four seats to support the ball, and to provide positive shutoff at any closed port. Multiple Gland Packing Seal & Spring Washer gives zero leakage from gland portion.
