It features a double locking mechanism consisting of a snap lock and ball lock system to assure that the ports are permanently locked closed after cementing is completed. Internal parts are designed to lock to prevent rotation during drill out and are constructed of easily drillable materials.3) Featuresa. Opening pressure can be adjusted and it is not subjective to hole angle.b. The pressure-relief design prevents fluid trapping and compression during the closing phase of the tool's operation.c. The I.D of upper/lower sub is the same as that of casing, but smaller than that of closing sleeve, which can minimize chances of damages to the closing sleeve.d.
