Product Detail
Product Description
Features
1. The middle flange bolt connection is adopted, and the two ends of the branch pipe are flange connection or butt welding connection.2. The opening and closing parts are forcedly sealed by semi-sealing pair, with excellent performance.3. The material of the sealing pair is wear-resistant ceramic or wear-resistant alloy, which has strong wear resistance, strong wear resistance, durable erosion, scratch resistance, low friction, and reliable sealing.4. The outlet flow passage of the valve body has a reasonable structure, no slag, flexible opening and closing, and no jamming.5. The valve stem is quenched and tempered and surface nitrided, which has good corrosion resistance, scratch resistance and wear resistance.6. The medium and large diameters are equipped with rolling bearings, which can be easily opened and closed.Main performance specifications
