5500 Series Lubricated Balancing Plug Valve

Our 5500 Series, lubricated balanced plug valve features a zero leakage tapered plug. It can also be adjusted inline, extending the service life of the valve. No sludge or slurry will accumulate because of the zero cavity design which has no dead space in the flow path. The 5500 Series also comes with pressure balancing system that keeps the pressure above the plug equal to the pressure of the plug port. Available from 1/2″ to 24″ and ANSI Class 150 to 1500.

  • Zero leakage: tapered plug valve assures positive bubble-tight shutoff with unique sealant system
  • Zero maintenance: tapered plug valve can be adjusted with the valve inline, extending the service life of the valve
  • Zero cavity: slurry or sludge doesn’t accumulate anywhere in the valve, because the valve has no dead cavity in the flow path
  • Pressure balancing system: for maintaining pressure equalization between plug port and bottom of the plug, and for insuring the pressure above the plug being the same or greater than in the plug port, the valve’s pressure balance system design is available
