Full Bore Retrievable Circulating Valve Drill Stem Testing Bypass Valve

The RTTS circulating valve is a locked-open/locked-closed valve that serves as both a circulating valve and bypass for the drill stem testing operation. The RTTS circluating valve is used with RTTS packer during operation, 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 RTTS circulating valve can be locked closed when the packer is unset to reverse fluid around the bottom of the packer.
* The RTTS circulating valve is designed with full opening allows tubing-type guns and other wire line equipment to pass.
