The Tubing Tester Valve (TTV) is an annular rupture disc controlled pressure test valve used to pressure test the tubing or drill string.
As the TTV is run-in-hole, the tubing will automatically fill as the flapper mechanism acts as a check valve. At any depth, the string can be pressure tested by applying tubing pressure. To lock open the TTV, annular pressure is applied rupturing a disc to shift the internal mandrel and hold open the flapper.
