An asymmetrical check valve has an inlet end, a transition part and an outlet end, with a pair of vertical lips facing one another. The lips may be flat or they may be curvilinear. The check valve is asymmetric about a horizontal longitudinal plane through the check valve. The bottoms of the transition part and outlet end may be aligned, with a major portion of the lips extending above the horizontal plane. It is thus possible to install conventional or wide bill check valves in installations with little or no clearance between the outlet end and ground level.

Clapet de retenue asymétrique composé d'une extrémité d'entrée, d'une partie de transition et d'une extrémité de sortie, ainsi que d'une paire de lèvres verticales placées vis-à-vis l'une de l'autre. Les lèvres peuvent être plates ou curvilignes. Le clapet de retenue est asymétrique autour d'un plan longitudinal horizontal de part en part. Les fonds de la partie de transition et de l'extrémité de sortie peuvent être alignés, et la partie principale des lèvres se prolonge au-dessus du plan horizontal. Il est ainsi possible d'installer des clapets de retenue classiques ou à bec large dans des installations ayant peu ou aucun jeu entre l'extrémité de sortie et le niveau du sol.
