摘要：

A gate valve for positioning in the open upper end of a grain bin below the lid thereof which closes the open upper end of the grain bin. The gate valve permits grain to pass downwardly therethrough but which prevents warm moist air from the grain bin from passing upwardly therethrough into a grain spout or deadhead box.
