a second valve portion comprising a sleeve, a second bore and a valve outlet,
wherein the stem and the sleeve engaged by a threaded connection,
wherein the first bore and the second bore form a channel to transport fluid from the inlet in the first valve portion to the valve outlet in the second valve portion,
wherein the sleeve encircles the stem and is adapted to close off the channel to prevent drainage of fluid,
wherein the distal end closure of the first valve portion is adapted to close off the valve outlet of the second valve portion,
