Globe-check Valve

A valve with one inlet and one outlet connection designed for precise, adjustable control of the flow in one direction and free flow in the opposite direction. Precise control is provided by a threaded needle or stem which is lifted perpendicularly off the center axis of its seat. Free flow is provided by an internal by-pass check valve which operates independently of the needle or stem.
