Abstract
A check valve is provided which may be installed horizontally or in other non-vertical orientations, and used with variable frequency drives and other applications without the valve disk becoming misaligned. In one aspect, the valve provides a housing with an inner surface and a passage, a flange within the housing which divides the housing into upstream and downstream portions, and extending around the inner surface, defining a valve seat and a valve aperture, a poppet positioned in the downstream portion, including a valve disk and a valve stem extending from the valve disk, the valve disk engaging the valve seat, being moveable, and being resiliently biased in the closed position against the valve seat to inhibit fluid flow in a first direction, and a guide removably mounted on the inner surface of the housing, the guide receiving the valve stem of the poppet valve as the poppet valve moves.
