One-piece, full-strength mandrel

Availability with 11- or 16-in-OD sleeve

Balls retained on seats in tool

Sixteen 0.437-in jet nozzles at 22° phasing

Clean close to the profile for optimal debris removal

The DUAL-ACTION BYPASS SUB circulating valve removes debris from the riser, blowout preventer (BOP), and wellhead to clean surfaces while preparing for cementing and completion operations. The tool is ideal for BOP jetting and specially designed to remove contaminants such as drill cuttings and mudcake that can impede effective cementing and completions.

The valve is run in the open position for jetting and cleaning while traveling through the BOPs, wellhead, and riser. The external jetting nozzles on the sub are then closed by dropping an actuator ball to allow flow through the sub and to circulate the string. By dropping another ball, they are reopened when pulling out, allowing jetting of the riser and BOPs. The balls remain on seat at all times.
