  • Patent number: 10077631
    Abstract: An equalizer valve is hydraulically operated by a pair of control lines running from a remote location such as a well surface. The use of control lines to make a mandrel or piston move in opposed directions removes the need for a spring or compressed gas to act as a spring against the anticipated hydrostatic force in a single control line system that is dependent on setting depth. The equalizer valve with its pair of control lines is insensitive to setting depth. Three seals on the mandrel are used to move the mandrel with the two control lines in opposed directions and to apply a net force to the mandrel. The seal applying the net closure force is exposed to a low or atmospheric chamber to make the second seal operate reliably using a large differential.
