Looking to control, divert, or mix flow from one valve instead of installing multiple valves and fittings? The 3-Way Ball Valve is your smartest solution. At Perfect Engineers, we manufacture industrial-grade L-Port and T-Port 3-Way Ball Valves designed for applications that demand multi-directional flow, mixing, or distribution—with just a single actuator or handle.
These valves are extensively used in chemical processing, water treatment, paints, inks, pharma dosing systems, and other industries where compact, flexible piping layouts are needed.
A 3-Way Ball Valve has three ports (inlet/outlets) and a ball with a cut-out path to control how fluid flows between them. The internal ball design defines the valve’s operation, which comes in two main types:
| Parameter | Specification |
|---|---|
| Size Range | ½” to 6” |
| Pressure Rating | Up to PN100 / Class 600 |
| Seat Options | PTFE, RPTFE, Graphite, Metal Seated |
| Body Materials | SS304, SS316, WCB, PVC, Brass |
| Flow Type | L-Port or T-Port |
| End Connections | BSP/NPT Threaded, Flanged, SW, Clamp |
| Operation | Manual, Pneumatic, Electric |
| Mounting | ISO 5211 Actuator-Ready |

We supply 3-way ball valves with:
L-Port is ideal for selecting between tanks or sources.
Absolutely. All our models are ISO 5211 compatible.
Use SS316 or Hastelloy body, with RPTFE seats for corrosive media.
Ball valves offer better sealing, lower torque, and wider media compatibility
