General

The 7" Full bore retrievable Circulating valve / 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

The valve can be locked closed when the packer is unset to reverse fluid around the 

bottom of the packer.
