Shut Off Pig Valves

Pipeline intervention gadgets — abbreviated as “pig” — are crucial to maintaining modern mechanical systems in many industries. Operators rely on them to clean systems, control corrosion, identify pipeline blockages and more. 

The valves simplify the process of entry and exit by providing a built-in launching and recapturing point.

Available Shut-Off Pig Valves

Shut-off pig valves feature a through-conduit style that distinguishes them from other models. While some gate or check valves can become “piggable” with a specialized insert, the shut-off pig valve has a trunnion-mounted ball at the heart of its design. Their flexibility allows them to play the role of launcher or receiver.
