Three-Way Ball Valve - Diverting and Mixing Duty

Three-way flanged ball valve in 304/316L stainless steel with L-port and T-port flow options. PN16/ANSI 150 flanges, PTFE seats, pneumatic or manual operation available.

Model reference: Three-Way Flanged Stainless Steel Ball Valve · size range DN15-DN100 · connection ANSI 150 / PN16 flange.

Key features

• L-port and T-port balls stocked for immediate delivery
• Heated-cavity option for crystallising or viscous media
• L-port for 90° diverting, T-port for combining or splitting flow
• Single quarter-turn changeover replaces two isolation valves
• Four-seat construction keeps the unused port bubble-tight
• Bottom-entry or side-entry stem, actuator-ready top flange
• Available in threaded, flanged, welded and clamp ends

Typical applications

• Temperature-control and mixing loops
• Tank switching and manifold stations
• Heat-exchanger changeover
• Filtration skids with duty/standby filters
• Sanitary diversion in food and pharma lines

Materials and standards

Body: CF8M / 316L; ports: 3 × full bore; ball: L-port or T-port; pressure 1000 PSI (PN63) threaded, PN16 flanged; temperature -20 °C to +180 °C; actuator mounting ISO 5211; testing per API 598. All wetted parts are traceable to EN 10204 3.1 mill certificates, and each valve is pressure-tested before packing.

Frequently asked questions

Should I choose L-port or T-port?
L-port diverts flow from one inlet to either of two outlets - ideal for changeover. T-port connects all three ports and is used for mixing, splitting or bypass.

Can one actuator drive the changeover?
Yes. A 90° pneumatic or electric actuator mounted on the ISO 5211 pad performs the changeover, with a 180° version available for T-port mixing duty.
