The ZPR780F Pneumatic Vertical Stem Flanged Discharge Ball Valve is a compact structure designed valve for discharge of tank material,short distance between the valve seat and end flange,effectively eliminating any residual medium typically found at the container outlet. As a specialized shut-off valve predominantly employed in various storage containers’ bottom.  Widely applied in polymerization reactions, chemical fiber production, food processing,fermentation processes, and other industries; it also proves to be an ideal choice for slurry material and high-density fluid applications.When selecting valves from this series, it is crucial to consider factors such as temperature, pressure levels, adhesion properties, corrosiveness of the medium within the storage container to optimize performance under different operating conditions.
