Brief Description Of The Advantages Of Trunnion Mounted Ball Valve

The advantages of Lined Ball Valve are:
1. Emergency grease injection rescue for sealing: If the valve seat seal fails unexpectedly due to foreign matter in the medium or fire, the grease injection valve provides a quick connection with the grease injection gun, which can easily and quickly inject the sealing grease into the valve seat sealing part to alleviate leakage.
2. Reliable valve stem seal and low operating torque: In addition to the standard sealing ring, an "O" type sealing ring is also set on the packing gland. The double seal ensures the reliability of the valve stem seal; the additional graphite packing and sealing grease injection minimize the valve stem leakage after the fire. The valve stem sliding bearing and thrust bearing make the valve easy to operate.
3. Full bore or reduced bore: Full bore or reduced bore structure can be selected according to needs. The flow aperture of the full bore valve is consistent with the inner diameter of the pipeline, which is convenient for pipeline cleaning.
4. The valve stem can be lengthened: The valve stem can be lengthened according to the needs of installation or operation. The extended stem ball valve is particularly suitable for occasions such as city gas where pipelines need to be laid underground. The lengthened valve stem size is determined according to customer needs.
5. Flexible operation: The valve seat and stem bearings with small friction coefficient and good self-lubrication greatly reduce the operating torque of the valve. Therefore, even without providing sealing grease, the valve can be operated flexibly for a long time.
