The electric discharge valve is a specially designed discharge ball valve that uses a spherical closure element with a circular passageway. The ball rotates with the valve stem to open or close the passageway, thereby achieving the purpose of opening or closing the flow path. The valve seat is positioned close to the end flange, minimizing material retention, featuring a compact structure, and providing excellent sealing performance. It is primarily used in the fine chemical, pharmaceutical, and chemical industries, and can also be used for conveying fine, soft granular media. With the adoption of PPL sealing material, it offers enhanced wear resistance, making it an ideal solution for vacuum discharge applications.
