When your pipeline demands unrestricted flow, minimal pressure loss, and zero media buildup, a Full Bore Ball Valve (also called Full Port Ball Valve) is the ideal solution. At Perfect Engineers, we manufacture a wide range of full bore ball valves in stainless steel, carbon steel, brass, and polymer materials, suitable for critical flow applications in water, oil, gas, food, pharma, and chemical industries.
A Full Bore Ball Valve is designed with an internal bore (opening) that matches the exact diameter of the connecting pipe. This ensures no reduction in flow area, allowing fluids or gases to pass through without restriction.
The full bore design prevents:

| Feature | Full Bore Valve | Reduced Bore Valve |
|---|---|---|
| Flow Area | Matches pipe ID | Smaller than pipe ID |
| Pressure Drop | Negligible | Moderate |
| Pigging Compatibility | Yes | No |
| Best For | High-flow, clean systems | General shut-off |
| Cost | (Slightly higher) | (Budget-friendly) |
Slightly—but offer longer life, better flow, and lower energy loss.
Yes! Full bore valves allow pigs (cleaning devices) to pass through without obstruction.
Yes—when made with SS316L, TFM seats, and cavity-free design.
Full bore is ideal. Choose metal-seated or cavity-filled design for durability.
