Side Entry Ball Valve

A Side Entry Ball Valve is an industrial quarter-turn shut-off valve engineered with a split-body design, typically offered in two-piece or three-piece configurations. The ball is installed from the side of the valve body during manufacturing, enhancing structural integrity and making maintenance faster and more convenient. This design allows internal components such as seats, seals, and the ball to be inspected or replaced without removing the entire valve from the pipeline, reducing downtime and operational costs. Side entry ball valves provide tight sealing, low torque operation, and excellent control over liquids, gases, and corrosive media. They support full-bore and reduced-bore options, ensuring optimal flow characteristics with minimal pressure drop. Due to their durability and ability to withstand high pressures and temperatures, they are widely used in oil & gas, petrochemical, chemical processing, power generation, marine, and water treatment industries. These valves comply with global standards such as API 6D/608, ISO 5211, ASME, and EN, and can be automated with pneumatic, electric, or hydraulic actuators. Their robust body construction, anti-blowout stem design, and fire-safe certifications make them suitable for critical and hazardous applications.
