7" RTTS Circulating Valve Full Bore Retrievable Circulating Valve
The RTTS Circulating Valve is a Full Bore Retrievable Circulating Valve in Halliburton type. The RTTS circulating valve is applied for drill stem testing string with RTTS packer and the RTTS circulating valve can be locked closed when the packer is unset to reverse fluid around the bottom of the packer. The full bore design of the RTTS circulating valve allows tubing-type guns and other wire line equipment to pass.
Operation of RTTS Circulating Valve
When the RTTS Circulating Valve is placed in the hole, the valve must be in the locked open position. The J-slot in the packer-body drag block (or drag sleeve) must also be placed in the unset position.When the circulating valve is opened to come out of the hole, the tubing is lowered, turned to the right, and picked up. The operating principle of RTTS Circulating Valve is based on lug movements in a J-slot. The lugs move with workstring manipulation. When the lug is in the upper position, the circulating valve is open; when the lug is in the lower position, the circulating valve is closed.

﹡HSE﹡Safety Testing instructions of RTTS Circulating valve
1. When running each pressure test, you must increase pressure gradually. When the pressure is up to 20MPa, hold on for one minute, then every 10MPa keep it for one minute until the rating pressure;
2. During doing the pressure test, the tool should be placed in the test pit and cover the protecting board on the pressure test plug.
3.During the whole process, make sure the entire test operator keep away from plug and joint which may lapse.
4.Test area should set isolation, others except operator not allowed to enter test area.
5.If there is anybody in the test area, it should set isolation, avoiding test production fly off the test area.
