One. Structure and characteristics

1. The middle flange bolt connection is adopted, and the two ends of the branch pipe are flanged or butt-welded.

2. The opening and closing parts are forcedly sealed by a semi-sealed pair with excellent performance.

3. The sealing pair material is wear-resistant ceramic or wear-resistant alloy, with strong wear resistance, strong wear resistance, durable erosion, scratch resistance, low friction, and reliable sealing.

4. The outlet flow path of the valve body has a reasonable structure, no slag, and flexible opening and closing.

5. After quenching and tempering and surface nitriding treatment, the valve stem has good corrosion resistance, scratch resistance and wear resistance.
