Advantages of Fully Lined Plug Valve & Sleeved Plug Valve:
1. Working media flowing directly, fully lined plug valve and sleeved plug valve
have the advantages of small pressure loss and faster operating speed. What's more, with just 90 degrees rotation, the conical plunger can easily make on and off action.
2. Made from PTFE and other plastic material, fully liner has the function of self-lubrication. Therefore, there will be a small sealing friction coefficient in the work with flexible operation.
3. The dual-channel trench sealing ring can not only make the PTFE liner or fully liner steady in the valve body, but also absorb small changes of liners caused by temperature changes. Also, friction, between the liner and cock, extends the life of the sealing surface.
4. Made from PTFE and other plastic material, the liner-type seat ring, with easy site maintenance and replacement advantages, improves the service life of plug valves.
