Abstract: A pipeline assembly includes a hollow body having a first opening and a second opening. A valve port fluidly coupled to the first opening is provided on the body and a valve port seat is disposed in the valve port. A shutter is urged against the valve port seat by a spring fluidly de-coupling the second opening from the first opening and the valve port. A valve plug includes a check valve. When the valve plug is disposed in the valve port, the valve plug decouples the shutter from the valve port seat to fluidly couple the first opening and the second opening with a fluid flow in only a first direction when the check valve is in an open condition.
