1. A coaxial valve system comprising an interior valve and an exterior valve wherein;
the interior valve comprises an elongated shape having a central axis;
the exterior valve comprises an elongated shape having a central axis;
the central axis of the interior valve and the central axis of the exterior valve comprising a coaxial alignment wherein the interior valve interposes within the exterior valve; and
the interior valve and the exterior valve have the capability to linearly move independently along the coaxial axes,
wherein the interior valve comprises a rod, a top plate integrally connected to one end of the rod,
wherein the exterior valve comprises a through hole proximate the central axis through which the rod of the interior valve transverses a length of a central portion of the exterior valve,
wherein a cutout in an upper portion of the exterior valve is configured to limit movement of the interior valve to a movement along the central axis of the interior valve and, together with the top plate, to prevent rotation of the interior valve within the exterior valve.
