TECHNICAL DATA SHEET
Motorized 3‑Way Ball Valve
L‑Port / T‑Port · Electric Actuated · Multiport Flow Control
The Motorized 3‑Way Ball Valve is a multiport quarter‑turn valve designed for flow diversion, mixing, or shut‑off in three‑pipe systems. With a specially ported ball core (L‑port or T‑port configuration), the valve enables selective switching of media between two outlet ports or merging of two inlet streams into a common outlet, all within a single compact body.
The electric actuator provides automated, remote‑controlled operation, making this valve ideal for HVAC, chemical dosing, heat exchanger bypass, water treatment, and industrial process control. By replacing multiple two‑way valves, the 3‑way ball valve simplifies piping, reduces installation footprint, and lowers system cost while maintaining bubble‑tight shut‑off and reliable performance.

Configuration | Flow Path Description | Typical Application |
L‑Port | The ball has two passages that connect adjacent ports in a 90° rotation; switches flow from one common inlet to either of two outlets (or vice versa). | Flow diversion / selector valve – e.g., switching feed between two heat exchangers. |
T‑Port | The ball has three interconnected passages; can mix two inlet streams into one outlet, or divert one inlet to either outlet, or provide full bypass. | Blending, mixing, or bypass control in HVAC and process lines. |
Standard rotation: 90° for L‑port; 180° for full T‑port functionality (some designs use 90° for T‑port partial opening).
