Abstract
An angle of repose valve for controlling the flow of granules and a method of repairing a leak in an angle of repose valve are disclosed herein. The angle of repose valve has a housing with an interior cavity, an inlet, and an outlet. A gas is used to convey granules through the valve and the housing has a thickness such that the gas can have a pressure of at least 70 psi. A saddle is disposed in the interior cavity of the housing and is coupled to a rotatable shaft that passes through an opening in the housing. A chevron seal is disposed between the shaft and a sealing member. A compression member is threadably engaged with the sealing member and is operable to exert force on the chevron seal to expand the chevron seal against the shaft and/or the housing to prevent and/or repair leaks of gas therethrough.
