1. The length of the ultra short structure and material saving can greatly reduce the overall weight of the pipeline system.

2. Small occupancy space can effectively support the strength of the pipeline and reduce the possibility of pipeline vibration.

3. Choosing austenitic stainless steel for the gate plate can greatly improve the corrosion resistance and effectively prevent the sealing leakage caused by the corrosion of the gate plate.

4. The upper sealing packing adopts flexible PTFE, which is reliable and easy to operate.

5. The gate has the function of the knife, and can effectively break all kinds of debris in the medium.

6. If the material of stainless steel with hard seal is used and the valve disc is treated by spray welding, the temperature and pressure requirements of the valve can be well extended.
