A valve that uses a rotating cylindrical or tapered plug to either stop or allow the flow of fluids.
Metal Type Lubricated Plug Valves
Tapered plug valve assures positive bubble tight shut off with unique sealant system.
Tapered plug valve can be adjusted with the valve line, extending the service life f the valve.
Slutty or sludge don’t accumulate anywhere in a valve, because valve has no dead cavity i the flow path.
Positive quarter turn on operation is quick and sure.
For maintaining pressure equalization between plug port and bottom of the plug, and for insuring the pressure above the plug the same as or greater in the plug port, pressure balance system design is available.
① As taper plug and Teflon sleeve contact face to gives absolutely no leakage. ② Steam Seal Structure has been designed to complement the controversial point of other plug valves. ③ As Steam Seal is not exposed externally it doesn’t rust and able to increase life span.
No dead space in the fluid way can allow control of open / close function and gives semi-permanent life span.
① No dead space doesn’t allow fluid to be clogged up. ② Re-adjusting of Seal Pressure by using Adjusting-Bolt After abrasion of Teflon Sleeve gives semi-permanent sealing function. ③ Metal lib around port has Self-Cleaning function to control steamy and solid material liquid. ④ Top Entry type can allow to be repaired on line.
