Description
1. The product design conforms to standards NB/T 47044 and ASME B16.34.
2. The stem is hardened and nitrided, providing heat resistance, wear resistance, and high corrosion resistance.
3. Erosion-Resistant Components: Nitrided, erosion-resistant seat, disc, and protective sleeve are employed; these components are replaceable.
4. Top inlet/bottom outlet design ensures low opening/closing torque and easy operation.
5. The sealing surfaces of the seat and disc are overlay welded with cobalt-based hard alloy or plasma sprayed, offering high heat resistance, wear resistance, and galling resistance.
6. The body features a forged design.
