“THE NEW DIRECTION IN PIGGABLE WYE TECHNOLOGY”
DUAL DIRECTOR™ BI-DIRECTIONAL PIGGABLE WYE
The Dual Director™ Bi-Directional Piggable Wye has the unique ability to accommodate bi-directional and/or
reverse flow pigging through both the main line and lateral line of the wye due to a unique internal diverting
mechanism that can be actuated via external torque bucket by ROV, hydraulic actuator, or diver. Activating
the diverter sleeve in the main line rotates the sleeve to close the port to the lateral line, permitting bi-
directional pigging in the main line. Activating the diverter sleeve in the lateral line rotates the sleeve to close
the port to the main line, permitting bi-directional pigging in the lateral line. When both diverter sleeves are in
the open position the Dual Director’s™ unique design permits conventional flow combining pigging operations.
Also Available: Director™ Bi-Directional Piggable Wye which only permits bi-directional pigging through the
main line of the wye.
