A one-way flow valve is provided wherein the one-way flow valve may comprise a first section and a second section of a housing. A valve member may be disposed between the first and second sections of the housing that permit fluid flow through one direction of the one-way flow valve but prevents fluid from flowing in the reverse direction. The opening pressure (i.e., the pressure differential across the valve member) to permit flow through the one-way flow valve may be increased or decreased by inserting (e.g., threadably engaging) the second section of the housing deeper into the first section of the housing or withdrawing (e.g., threadably disengaging) the second section of the housing from the first section of the housing.
