LUBRICATED PLUG VALVE

(PRESSURE BALANCE PLUG VALVE):

 

Lubricated Plug Valves (Pressure Balanced) are available in Regular, Short or Venturi Pattern as per API 6D and API 599. Regular Pattern valves have the largest port area. Short Pattern valves have a reduced port area as a consequence of their compact face-to-face dimensions which are identical to those for wedge gate valves. Venturi Pattern valves have a reduced port area and a flow path approximating a venturi shape to aid pressure recovery.

This plug valve is widely used throughout industry, particularly in chemical processing where there are corrosive materials. It is leak tight, rugged and reliable, with low resistance to flow but high resistance to corrosion and erosion.These valves are maintained externally by injecting sealants during normal working so there is no need for plant shut-downs.
