9 5/8" x 10000psi Full bore retrievable circulating valve
DST RTTS circulating valve
Introducation of the full bore retrievable circulating valve
The RTTS circulating valve is a locked-open/locked-closed type that serves as both a circulating valve and bypass valve.
70Mpa working pressure 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 valve can be locked closed when the packer is unset to reverse fluid around the bottom of the packer. The tool's
full opening allows tubing-type guns and other wire line equipment to pass.
