1. An integrated pressure management apparatus comprising:

  • a housing defining a fluid communication passage between first and second fluid ports, the housing including a first portion extending along an axis, the first portion having a first surface parallel to the axis;

    a poppet being movable between first and second configurations, the first configuration preventing fluid communication between the first and second ports, and the second configuration permitting fluid communication between the first and second ports, the poppet including;

    a second portion being translatable along the axis relative to the housing, the second portion including a tubular stem having a second surface parallel to the axis, the second portion nesting with the first portion so as to define a first gap between the first and second surfaces; and

    a head fixed to the tubular stem, the head contiguously engaging the housing so as to occlude the fluid communication passage when the poppet is in the first configuration; and

    a chamber being defined by the first and second portions, and the first gap communicating fluid between the chamber and the fluid communication passage.
