А full port ball valve (also called full bore ball valve) is a type of ball valve designed with an oversized ball and flow passage to minimize flow restriction. Unlike standard (reduced port) ball valves, the internal diameter of a full port valve matches the pipe diameter, allowing for unrestricted flow and lower pressure drop.

Key Features of Full Port Ball Valves

✔ Larger Ball & Bore – The hole (bore) through the ball is the same size as the pipeline.
✔ Minimal Pressure Drop – Smooth, unrestricted flow reduces turbulence and energy loss.
✔ Better for Slurries & Thick Fluids – Prevents clogging in viscous or particle-laden media.
✔ Bi-Directional Flow – Can handle flow in either direction.
✔ Quarter-Turn Operation – Opens/closes with a 90° turn (like all ball valves).


Full Port vs. Reduced Port Ball Valves

ПриложенияHigh-flow, slurries, viscous fluidsGeneral-purpose, clean liquids/gases

Applications of Full Port Ball Valves

  • Oil & Gas Pipelines – Minimizes pressure loss in long-distance transport.

  • Химическая обработка – Handles corrosive or abrasive fluids without clogging.

  • Water & Wastewater – Ideal for slurries and sewage with solids.

  • HVAC & Hydronic Systems – Ensures maximum flow efficiency.

  • Food & Beverage – Sanitary designs for high-purity liquid transfer.


When to Choose a Full Port Ball Valve?

✅ Required: High flow efficiency, minimal pressure drop.
✅ Fluids: Slurries, viscous liquids, or gases with particulates.
✅ System: Critical applications where flow restriction is unacceptable.

❌ Avoid If: Cost is a major concern, and flow restriction is tolerable (e.g., low-pressure water lines).


Final Verdict

А full port ball valve is the best choice when unrestricted flow is critical, while a reduced port valve is sufficient for general-purpose use.
