Non-lubricated, Lubricated and Pressure balanced Plug Valves
Non-lubricating plug valves are used where maintenance must be kept to a minimum.
Lubricated Plug Valves have a better sealing thanks to the sealantor lubricant. The surfaces are protected from corrosion and the valve has lower torque. Due to this advanteges lubricated plug valves have a longerlife, are more resistantand betterfor corrosive media.
