Wear-resistant valve for transporting particulate matter and method of making

摘要

The present disclosure provides a valve (10) for controlling the flow of abrasive particles along a predetermined path from the outlet (20) of a hopper to a conveying line (27) in a particle collection or transportation system. The design of the valve reduces the occurrence of erosive wear resulting from contact with the flow of abrasive particles. A method of making the valve that enhances the hardness of localized areas in the valve that are subject to high wear conditions is also disclosed.
