1. The product is designed according to the NB/T47044 and ASME B16.34 standards.
2. The valve stem is tempered and chlorinated, offering high temperature resistance, wear resistance, and good corrosion resistance.
3. The valve body cavity adopts a pressure self-sealing structure (Welded Seal), where the higher the internal cavity pressure, the better the sealing performance.
4. The medium flow direction is high inlet and low outlet, and the valve disc adopts a double disc structure, characterized by low opening and closing torque and easy operation.
5. The valve seat and sealing surface are made of cobalt-based hard alloy overlay welding or plasma spray welding, providing high temperature resistance, wear resistance, and good anti-scratch performance.
