ABSTRACT:
An equalizing blank valve apparatus for use in a sidepocket mandrel in an underground well. The apparatus comprises a first body member and a second body member. The first body has a chamber therein, and the second body member has a proximal end, a distal end, a first orifice located proximate said proximal end, a second orifice located proximate said distal end, and a passageway therethrough communicating with the said first and second orifices. The second body member is configured such that said proximal end of the second body member and said first orifice are telescopically insertable into the chamber in the first body member. Means cooperating with the first and second body members is provided for substantially sealing said first orifice when said first orifice is inserted into the chamber in the first body member. Means is also provided for preventing said proximal end of the second body member from being removed from the chamber in the first body member.
