3-Way Multi-Port Ball Valve
Engineered for complex process manifold flow diversion (L-port 90°) and proportional mixing or splitting (T-port 180°/360°). Eliminates external bypass loops and multiple 2-way valves to reduce potential pipeline leak paths.

3-Way Multi-Port Ball Valve Standard & Engineered Models
TSV manufactures an engineered lineup of 3-Way Multi-Port Ball Valve configurations for global oil & gas transmission pipelines, refinery manifolds, power plants, and severe industrial processes. Each unit undergoes 100% hydrostatic and pneumatic factory acceptance testing before dispatch.
L-Port 90° Process Flow Diverter Ball Valve
Engineered for switching flow between two pipeline branches. Eliminates need for multiple 2-way valves and external tee fittings.
T-Port 180°/360° Flow Mixing & Proportioning Ball Valve
Offers 4 seat multi-directional flow configurations allowing mixing, splitting, or straight-through bypass without dead leg stagnation.
Electric Modulating Multi-Port 3-Way Valve
Equipped with intelligent 4-20mA positioner and electric actuator for proportional blending control in automated process plants.
High-Pressure Forged 3-Way Threaded / Socket Weld Valve
Forged A105/F316 body for hydraulic injection systems, chemical dosing skids, and high pressure instrument manifold routing.
Multi-Port Flow Diversion & L-Port / T-Port Flow Switching Mechanics
Engineered for complex process routing, continuous bypass loops, and automated blending manifolds with zero cross-port leakage.
100% Hydrostatic Acceptance
Every valve is pressure-tested per API 598 / API 6D Rate A with zero allowable bubble leakage prior to factory crating.
EN 10204 3.1 Certified
Certified Mill Test Reports (MTR) with optical emission spectrometer chemical composition and mechanical impact values.
Global OXY Approved Supplier
Audited and approved on the global master vendor list (#24) of Occidental Petroleum for severe upstream duties.
