The present invention relates to a light weight check valve for use in bulk material transfers that incorporates a smooth, generally spherical interior cavity to minimize flow inefficiencies. The check valve is made from two portions: a body portion and a lid assembly which is removably mounted to the body portion. The gate valve, or poppet, is hingedly mounted to the lid assembly. Hence, when the check valve assembly is opened for inspection, by removing the lid assembly, the poppet is removed along with the lid assembly, to allow for easy inspection of the poppet.
