The distinguishing feature of a flange ball valve is the inclusion of flanges on both ends of the valve body. These flanges allow the valve to be bolted directly onto a pipeline, forming a secure and leak-proof connection. The flanges typically conform to standard dimensions and specifications such as ANSI or API standards.
Flanged end ball valve
A flange ball valve is a type of industrial valve that controls the flow of fluid or gas through a pipeline. It consists of a spherical ball with a hole in the center, which acts as the closure element. The ball has a bore or port through which the fluid can pass when the valve is in the open position.

The flanges typically conform to standard dimensions and specifications such as ANSI or API standards.
The ball inside the valve is connected to a lever or actuator mechanism, which can be manually operated or automated. When the valve is in the closed position, the ball is rotated to block the flow, creating a tight seal. Turning the lever or actuator to the open position rotates the ball, aligning the bore with the pipeline, allowing the fluid to flow through.
Flange ball valves are commonly used in industries such as oil and gas, petrochemicals, water treatment, and HVAC systems. They offer several advantages, including:
Full bore design: Flange ball valves have a large bore, allowing for high flow rates and minimal pressure drop.
Quick and easy operation: The quarter-turn operation of the lever or actuator makes it easy to open or close the valve rapidly.
Excellent sealing capability: The spherical ball provides tight sealing against leakage when in the closed position.
Versatility: Flange ball valves can handle a wide range of fluids, including corrosive and abrasive media.
Durability: They are typically constructed from robust materials such as stainless steel, carbon steel, or brass, making them suitable for demanding environments.
Reliable performance: Flange ball valves are known for their reliability and low maintenance requirements.
It's important to note that flange ball valves come in different configurations, such as two-way (on-off) or multi-port valves for diverting flow in multiple directions. The specific design and features may vary based on the intended application and industry requirements .
