A Cooperative Service Valve includes a fitting connected to a valve body via a tube, a stem configured to fit within the valve body. The stem includes a stem first end having a first seal and configured to movably fit within a tube first end, a sealing portion connected to the stem first end and configured, in a first position, to provide a second seal between the sealing portion and an inner surface of the stem body, a fluid flow portion comprising openings for allowing liquid or gaseous media to pass through the Cooperative Service Valve when the stem is in a second position and a stem second end configured to secure a poppet guide, a poppet and a spring associated with the poppet that biases the poppet against a seal to yield a third seal. The first, second and third seals open and close in a particular order to allow or prevent fluid from flowing through the stem.
