Packard International’s F-type cup tester assemblies are designed to be attached to the drill string and lowered into the casing beneath the wellhead to pressure test the blowout preventer stack and the wellhead.

Packard’s Inside Blowout Preventer (IBOP) is used to provide shutoff of backflow during periods when the drill string is open. The valve is held with the dart in the open position to allow stabbing during backflow. After stabbing the flow is shut off by turning the release handle. The stab body is removed and the drill string can be reconnected to re-establish pressure stabilization. The valve can then be removed and returned to its ready state or it can be left in the drill string to ensure downward flow only.

The KV-1, Packard International’s innovative, one-piece kelly valve, is designed to provide a positive seal in the event of a kick and can be used as an upper kelly valve, lower kelly valve, safety valve, or mud saver.

Packard International rotary subs are designed and manufactured according to their application. These applications include (but are not limited to) connection crossover subs, saver subs, side entry subs, pump-in subs, circulating subs, lifting subs, impression blocks, reduced section subs, bit subs, swivel subs, etc.

Packard safety valves are designed to either stab into the drill pipe or tubing at the rig floor or are used as part of the drill string to shut off a well kick. Use of these valves in the drill string enhances rig safety.
