Abstract (en)

The present application discloses a device for controlling a passage of fluid in a tubing string. The device comprises a fluid chamber and two pistons for interacting with a fluid inside the fluid chamber. Each piston is adapted for catching an object received through the tubing string from an uphole side of the device. Also, at least one of the pistons is adapted for controlling the passage of fluid, and the pistons and the fluid chamber are arranged so that the pistons are directed in the same direction along the tubing string.
