T-port valve balls, as known as 180-degree balls, are widely used to take two inlet flows and combine them to flow out through one common outlet port.

T-port valve balls can do more than splitting or dividing flow. They can act like L-port valve balls and divert flow from one outlet port to the other.

With the T-shape drilled bore, the fluid can be directed to more than one location simultaneously. When the ball is in the open position, fluid is allowed to pass through the valve at full pressure to A point while allowing fluid to go to B point with lower pressure. In this way, a T-port 3-way valve can direct fluid to multiple destinations.

In conclusion, T-port valve balls are very different from L-port valve ball. Normal designed T-port valve balls cannot provide shut-off control. They can either limit flow to any two of the three valve ports or allow flow through all three valve ports at the same time.
