T Port & L Port Three-Way Ball Valves
The three-way ball valve can be classified into T port type and L port type. What’s the difference between the two types?
A T port three-way ball valve can connect any pair of ports, even connect all three ports together. However, the L type three-way ball valve can only connect the center port with either side port or disconnect three ports, and it can not connect three ports together at the same time.
