The “SXO” Sliding Sleeve is a downhole flow control device mounted in the production tubing. It effectively controls the flow between the tubing and the casing annulus by means of an internal sleeve that can be opened or closed repeatedly.

Model “SXO” inner sleeve functions as DOWN to OPEN and UP to CLOSE.
