Full Bore Ball Valves are engineered to provide unrestricted flow paths, making them the go-to solution for applications where maximum flow efficiency is essential. Unlike reduced bore valves, the internal diameter of a full bore valve matches the pipeline size, eliminating turbulence and pressure drop. This design not only improves overall system performance but also allows for easy cleaning and pigging in process pipelines, which is especially beneficial in industries like oil & gas, chemical processing, and food and beverage manufacturing.

These valves are especially important in process lines that require cleaning or pigging, as the full bore design allows equipment to pass through the pipeline without disruption. They’re also vital in systems where precision and speed of shut-off matter — with their quarter-turn mechanism offering instant isolation. In short, Full Bore Ball Valves play a key role in maintaining operational efficiency, product quality, and long-term system performance.

Full Bore Ball Valves are commonly found in industries where maximum flow efficiency and minimal pressure drop are essential. These include water treatment facilities, oil and gas pipelines, food and beverage processing, chemical manufacturing, and HVAC systems. Their design allows for the full internal diameter of the pipe to remain unobstructed, making them ideal for transferring fluids, slurries, or gases without restricting throughput. In sectors like food production or pharmaceuticals, they are particularly valued for enabling hygienic cleaning processes such as pigging.

Industries

A full bore ball valve has an internal bore that matches the diameter of the pipeline. This allows for unrestricted flow with minimal pressure loss.

Full bore valves maintain the same diameter as the pipe, while reduced bore valves have a smaller internal diameter, which can restrict flow and increase pressure drop.

They’re widely used in industries like oil and gas, water treatment, chemical processing, food and beverage, and pharmaceuticals where full flow is essential.

Their full-bore design allows pipeline pigs to pass through without obstruction, making them ideal for cleaning and maintenance in hygienic or high-integrity systems.

Yes, many full bore ball valves are designed with ISO 5211 mounting pads, making them compatible with electric or pneumatic actuators.

Absolutely. Full bore ball valves are often constructed from durable materials like stainless steel or carbon steel and are pressure-rated for industrial use.

Yes, because they reduce pressure loss and turbulence, full bore valves can improve pump efficiency and lower energy costs in flow systems.

Yes, provided the valve is correctly rated for the pressure and media, they are suitable for use with natural gas, compressed air, and other gases.

They typically use a quarter-turn handle for manual operation, but can also be automated using actuators for remote control.

They come in a wide range of sizes, from small ¼” valves for lab or instrumentation use up to large industrial sizes for high-capacity pipelines.

Yes, their simple design with few moving parts makes them low-maintenance and reliable over long periods of use.

They are available in stainless steel, brass, carbon steel, PVC, and other materials depending on the application and media compatibility.

Full Bore Ball Valves

Why specify full bore?

A full bore ball valve has a bore that matches the pipe ID, giving the lowest pressure drop and the highest Cv for the line size, and allowing pigging and cleaning. Reduced bore valves are smaller and need less torque, but add a restriction. Read full bore vs reduced bore ball valves for the full comparison.

Full bore options include the BV-L4500 WRAS approved brass, BV-L2000 2 piece, BV-L3000 3 piece and BV-L8000FS heavy duty stainless ranges, flanged PN16, PN40 and ANSI 150 valves, and 3-way full bore valves.
