Flanged Ball Valve

Flanged ball valves are quarter-turn valves featuring integral flanges for direct, secure bolting into a pipeline. This design adheres to API 608 specifications for industrial valve construction, ensuring reliability. This flanged connection provides a high-integrity, zero-leakage seal ideal for mission-critical and high-pressure systems.

The valve body encloses a perforated, pivoting ball that rotates to control flow. The flange ends eliminate the need for threaded or welded connections, significantly reducing potential leak paths. This robust construction simplifies both installation and maintenance, allowing for easy removal and servicing without cutting the pipe. This feature is particularly valuable for applications requiring periodic inspection and component replacement. The ANSI Flange Ball valve design ensures interchangeability and dimensional consistency across manufacturers.

• Ensures secure, bolted connections compliant with ANSI standards.
• Provides tight shutoff with a quarter-turn mechanism for rapid operation.
• Reduces potential leak paths compared to threaded valve alternatives.
• Simplifies in-line maintenance and component replacement.

Unlike threaded valves, flanged models are better suited for larger pipe diameters such as 2″, 3″, 4″, and 6″, and higher pressure classes including 150Lb and 300Lb. While functionally similar to a Trunnion Ball valve, the floating ball valve design is often more cost-effective for standard service applications. For a detailed guide, see our Trunnion mounted VS floating Ball valve comparison.

Selecting the correct Flanged Ball Valve requires matching the material, pressure rating, and design to the specific application media and operating conditions. As leading manufacturers, Yinke follows stringent ISO 9001 quality management protocols for every product. This commitment ensures your selected valve delivers optimal performance, safety, and service life.

Our product line includes various configurations to meet diverse industrial needs. The 2 piece flanged ball valve offers a strong balance of robust construction and ease of maintenance. For corrosive environments, our Stainless Steel FLANGED BALL VALVES (SS 304/316) provide superior chemical resistance and durability. We also offer flanged bronze ball valve models for seawater, marine, and municipal water applications where corrosion is a primary concern. The correct flanged ball valve symbol on P&ID drawings is critical for specifying the right component.

• Features materials like Stainless Steel 316 and bronze for specific media compatibility.
• Offers pressure ratings from ANSI Class 150 to 900.
• Provides customizable options for seals, stems, and actuation.
• Includes full material traceability and testing certification upon request.

Flanged ball valves deliver reliable on/off isolation, but for throttling service, butterfly valves or forged steel gate valves are often the better choice. With proper repair and regular maintenance, their service life can be greatly extended. Backed by extensive expertise, our knowledge of flanged ball valves is just as strong as our proven experience with cast steel gate valves.
