What Is a Reduced Port Ball Valve?
A reduced port ball valve, also called a reduced bore ball valve, is a quarter-turn shut-off valve with an internal bore smaller than the pipeline inside diameter. Compared with a full port ball valve, the reduced port design provides a more compact body, lower weight and more economical manufacturing cost while still maintaining dependable shut-off performance.
As an experienced reduced port ball valve manufacturer, ZONCIC supplies carbon steel, stainless steel and alloy steel valves for industrial systems where full bore flow is not essential. A reduced port ball valve is often selected when buyers need a practical balance between performance, installation space and budget.
If your project also requires full flow capacity, you can visit our ball valve category or explore our full industrial valves range.

Frequently Asked Questions
What is the difference between a reduced port ball valve and a full port ball valve?
A reduced port ball valve has an internal bore smaller than the pipeline diameter, which makes the valve body more compact and economical. A full port ball valve has a bore closer to the pipeline diameter, which helps reduce pressure drop and supports higher flow capacity.
Why choose a reduced port ball valve?
A reduced port ball valve is often selected for its compact structure, lower weight and lower cost. It is a practical option when full bore flow is not required and a cost-effective shut-off solution is preferred.
What standards can your reduced port ball valves be manufactured to?
We can manufacture reduced port ball valves according to API, ASME, DIN, JIS and GOST standards depending on export market requirements and project specifications.
What materials are available for your reduced port ball valves?
We can supply reduced port ball valves in WCB, LCB, CF8, CF8M, stainless steel, carbon steel and alloy materials according to media and service conditions.
Do you offer customized reduced port ball valve solutions?
