Features of knife gate valve:
1. Ultra short structure length, material saving, can greatly reduce the overall weight of the pipeline system.
2. It can effectively support the strength of the pipeline and reduce the possibility of pipeline vibration.
3. Using austenitic stainless steel, the corrosion resistance is greatly improved, which can effectively prevent the sealing leakage caused by the corrosion of the ram.
4. Flexible PTFE is used as the upper sealing packing, which is reliable in sealing and light and flexible in operation.
5. The gate has the function of knife switch, which can effectively cut off all kinds of sundries in the medium.
6. If the hard sealing stainless steel material is used and the valve disc is spray welded, the requirements of temperature and pressure of the valve can be well expanded.

Advantages of knife gate valve:
1. The fluid resistance is small, and the sealing surface is less eroded and eroded by the medium.
2. It is easy to open and close.
3. The flow direction of the medium is not limited, the flow is not disturbed and the pressure is not reduced.
4. Durable and easy to use.
5. The utility model has the advantages of simple shape, short structure length and wide application range.
