CDB Lubricated Plug Valves

Description

Lubricated Plug Valves use special grease as lubricant in order to make their operation easier, over a wide range of pressure ratings. The lubricant is injected between the plug and the body’s internal surface to form a film reducing the friction and the torque during the rotation while sealing the valve at the same time. The proper grease is selected according to the process/application and is base oil with a viscosity improver. Depending on the use and number of cycles, the valves require a re-injection of the sealant to restore the lubricant film and sealing.
