1. The bearing adopts self-lubricating bearings with low friction resistance.
2. The butterfly seal ring can be replaced without disassembling the valve from the pipeline.
3. This valve can block the medium in both directions, achieving reliable sealing and zero leakage in both directions.
4. The shaft seal adopts a special structure with automatic compensation to block the connection between the external atmosphere and the pipeline, thereby ensuring the vacuum degree of the pipeline.
