Three-Way Ball Valve - Diverting and Mixing Duty

Three-way threaded ball valve for diverting and mixing duty. Stainless steel body, BSP/NPT threads, L or T port, rated to 1000 PSI. Available with electric or pneumatic actuator.

Model reference: Three-Way Threaded Ball Valve · size range DN15-DN50 · connection BSP / NPT threaded.

Key features

• Compact threaded body for small-bore mixing circuits
• Quarter-turn changeover with lockable lever
• 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.
