Product Features

1. Ultra-short face-to-face length saves materials and greatly reduces the overall weight of the piping system.

2. Occupies little effective space, effectively supports the structural strength of the pipeline, and reduces the possibility of pipeline vibration.

3. The gate is made of austenitic stainless steel, which greatly improves corrosion resistance and effectively prevents sealing leakage caused by gate corrosion.

4. The upper sealing packing uses flexible PTFE, ensuring reliable sealing and light, flexible operation.

5. The gate features a knife-edge function, effectively cutting off various impurities in the medium.

6. If hard-sealed stainless steel material is adopted and the disc is spray-welded, it can significantly extend the valve's applicable temperature and pressure ranges.
