Description

Pigging Ball Valve – API 6D, Flanged, Full Bore (Shut-off & Pigging Valve)

The Pigging Ball Valve is a multi-functional valve designed for efficient and safe pigging operations in pipeline systems. Integrating shut-off, venting, and bypass functions in a single unit, it ensures smooth pig launching and receiving while maintaining full pipeline isolation. Engineered for high-pressure and high-cycle conditions, this valve delivers reliable performance in oil, gas, and petrochemical applications.

The valve's design allows pipeline pressure to act on spring-loaded seats rather than the ball itself, ensuring stable, bubble-tight shut-off with reduced operating torque. Its full bore configuration provides minimal pressure drop and facilitates pigging operations, making it ideal for maintenance, inspection, and emergency bypass scenarios.

Equipped with pneumatic or electric actuation options, the valve supports automated and remote operation, enabling fast response and safe isolation during pigging or emergency shutdowns.

Key Features

Multi-functional design combining shut-off, venting, and bypass in one valve

Full bore configuration for smooth pig launching and receiving

Spring-loaded seats ensure bi-directional, bubble-tight sealing
