Durapipe 3-Way ball valves available in sizes ½" to 2" available.
T port and L port valves are similar in the fact they provide methods for diverting flow, however in function they are unique to each other.
The ball in a T port valve is drilled to have a T shaped bore. This allows fluid to be diverted to two outlets simultaneously or two inlets mixed to one outlet when the valve is fully open.
Conversely, the ball in a L port valve is drilled to have an L shaped bore. This means fluid can be fed from multiple sources but depending on the position of the handle, only one will be active. However, unlike a T port valve, an L port valve can be fully closed, restricting any flow.
