1. Adopting middle flange bolt connection, the two ends of the branch pipe are connected by flange or butt welding;

2. The opening and closing components adopt a semi sealed pair for forced sealing, with excellent performance;

3. The sealing material is wear-resistant ceramic or wear-resistant alloy, which has strong wear resistance, strong wear resistance, durable erosion resistance, scratch resistance, low friction force, and reliable sealing;

4. The outlet channel of the valve body has a reasonable structure, no residue, flexible opening and closing, and no jamming;

5. The valve stem has undergone quenching and surface nitriding treatment, which provides good corrosion resistance, scratch resistance, and wear resistance;

6. Large and medium diameter rolling bearings are installed for easy opening and closing.
