7″ x 10000 psi Full bore circulating vale

Drill stem testing tools

DST tools


The full bore Circulating valve is a locked-open/locked-losed 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.
