Performance characteristics

1. Ultra short structural length saves materials and greatly reduces the overall weight of the pipeline system.
2. Occupying a small effective space, it can effectively support the strength of the pipeline and reduce the possibility of pipeline vibration.
3. The gate plate is made of austenitic stainless steel, which greatly improves its corrosion resistance and can effectively prevent sealing leakage caused by gate plate corrosion.
4. The upper sealing packing is made of flexible PTFE, which is reliable in sealing and easy to operate.
5. The gate has the function of a "knife switch", which can effectively cut off various impurities in the medium.
