ABSTRACT:
An inversion-resistant check valve or tide gate valve which comprises a sleeve bounding in a longitudinally-extending flow-through passage for fluids. The sleeve has an upstream fluid inlet end region mountable on a discharge end of a conduit which is elongated along a longitudinal axis of symmetry. The sleeve also has a downstream fluid outlet end region comprised of two or more lips which are opposed to each other and symmetrically arranged relative to the axis, wherein the lips extend a defined length along the axis, the defined length being within the range of about 1:1.5 to 1:9 times the diameter of the conduit.
