What Are Flanged Ball Valves?

Flanged ball valves are a type of quarter-turn valve that uses a spherical ball to control the flow of liquids and gases. The flanged ends enable easy bolting to the pipe system, providing a secure, leak-proof connection ideal for high-pressure applications. These valves are widely used for their:

- Durability

- Ease of operation

- Tight sealing capabilities

- Low maintenance requirements

Industries such as oil & gas, water treatment, chemical processing, and offshore drilling extensively use these valves due to their ability to handle demanding conditions and ensure safe, reliable flow control.
