Introduction


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.
