Model MXo- MXO / MXa- MXA / MXd- MXD: A downhole flow control device mounted in the production tubing. It effectively controls the flow between the tubing and the casing annuals by means of internal sleeve that is opened and closed by standard wireline methods.

Model ML: A downhole flow control device mounted in the production tubing to provide communication between the tubing and casing annulus by equalizing pressures. It can be opened and closed using standard wireline methods and its internal profile allows landing of flow tools.
