The DirectorTM Bi-Directional Piggable Wye is capable of bi-directional and/or reverse flow pigging in the mainline of the Wye due to a unique internal diverting mechanism that can be actuated via a standard external torque bucket by ROV, hydraulic actuator, or diver. The Dual Director™ Bi-Directional Piggable Wye permits bi-directional pigging through both the mainline and the lateral legs of the Wye.
