Trans-Flow progressive distribution

The three-way ball valve Series 04 is a TRANS-FLOW valve with floating ball; when moving, all three ports of the valve are temporarily open, and as a result, the flow switches from one port to the other progressively.

These features mean that, for proper use, the pressure acts against the seat of the closed port, and NOT FROM THE CLOSED PORT SIDE

In this case, leakage and ball seat damage may occur.
