Briefly Introduce:  

The Full bore retrievable (RTTS) Circulating valve is a locked-open/locked-closed valve that serves as both a circulating valve and bypass. The clearance between the RTTS packer (or any hookwall packer) and the casing ID is relatively small. To reduce the effect of fluid-swabbing action when the tool is run in or pulled out of the hole, a packer bypass is generally used.





Features and Benefits

• The full-opening design of the packer mandrel bore allows large volumes of fluid to pump through the tool. Tubing-type guns and other wireline tools can be run through the circulating valve.

• The valve can be locked closed when the packer is unset to reverse fluid around the bottom of the packer.
