Cone Valve

The cone valve is used in conjunction with the charging hopper as the main inlet and sealing valve for the conveying system. The charging hopper’s design eliminates head pressure, and vents the displaced air when material fills the pressure vessel, thus allowing the single cone valve to completely seal the pressure vessel once full. Unlike a butterfly valve, the cone valve’s seals actually become tighter during pressurization. It is not uncommon for a Dense Flow cone valve to last 15 years or more before needing a seal replacement
