The present invention relates to a system and a pressure activated valve for preventing fluid from passing through an ICD during installation and commissioning of a production string in a well bore. Further the invention relates to a method for operating the pressure activated valve. The pressure activated valve can be arranged outside the production string being configured to hinder fluid from entering the ICD from a reservoir when the pressure activated valve is closed and to allow fluid from entering from the reservoir when pressure activated valve is open.
